House passes legislation requiring SBA offices to leave ‘sanctuary cities’

 

The House passed a bill Thursday that would remove Small Business Administration offices from “sanctuary cities” that limit cooperation with federal immigration authorities, like New York, Boston, Denver and Chicago.

 

The legislation passed 211-199.

 

The bill, H.R. 2931, would codify administrative action that SBA Administrator Kelly Loeffler debuted in March that congressional Republicans were aligned with. As part of that action, Loeffler said she would move regional SBA offices out of six “sanctuary cities” — Atlanta, Boston, Chicago, Denver, New York City, and Seattle — “to less costly, more accessible locations that better serve the small business community and comply with federal immigration law.”

 

The House legislation would require Loeffler to relocate SBA offices from any “sanctuary jurisdiction.” The bill leaves any additional sanctuary city relocations up to Loeffler.

 

House Small Business Chair Roger Williams (R-Texas) said the six regional offices Loeffler has already identified for relocation will be moved to “safer communities” in those same states.

 

“It is important to note that SBA services to small businesses nationwide will not be interrupted by passing this legislation,” Williams said on the House floor.

 

Democrats, however, disputed that the bill would cause disruptions for small businesses.

 

“This bill does nothing to help small businesses and is all about punishing cities for their politics. It targets our nation’s major economic hubs where small businesses rely on in-person SBA support. Uprooting those offices is disruptive, expensive, and purely political,” said House Small Business Ranking Member Nydia Velázquez (D-N.Y.).

 

The House also passed by a vote of 214-198, H. R. 2987, the CEASE Act, a bill capping the number of for-profit small business lending companies that can make loans under SBA’s primary lending program.

Biden’s White House physician subpoenaed for deposition by House Oversight Chair

 

House Oversight Chair James Comer has subpoenaed former President Joe Biden’s White House physician to appear for a deposition later this month, according to a copy of the subpoena letter shared with CNN.

 

The subpoena to Dr. Kevin O’Connor marks an escalation of the Republican chairman’s probe into Biden’s mental fitness and decline.

 

In the subpoena letter, Comer said O’Connor was not complying with the committee’s initial voluntary request for a transcribed interview.

 

The letter from Comer states that counsel for O’Connor responded to the committee’s request for testimony, saying that the physician can’t appear for the requested interview, citing legal and ethical obligations as well as “physician-patient privilege.” The letter from Comer says that “these arguments lack merit.”

 

CNN has reached out to O’Connor for comment.

 

The subpoena comes as President Donald Trump ordered an investigation into Biden’s actions and autopen use in a Wednesday memorandum that cites his predecessor’s “cognitive decline.”

 

Biden dismissed the suggestions in Trump’s memo, saying in a statement Wednesday evening, “Let me be clear: I made the decisions during my presidency. I made the decisions about the pardons, executive orders, legislation, and proclamations. Any suggestion that I didn’t is ridiculous and false.”

 

The former president went on to call his successor’s executive action a “distraction.”

 

Comer has ramped up his investigation into Biden’s mental fitness in recent days, requesting interviews with nearly a dozen former key aides.

Chairman Comer Subpoenas Dr. O’Connor Over Cover-Up Of Biden’s Mental Decline

 

WASHINGTON—House Committee on Oversight and Government Reform Committee Chairman James Comer (R-Ky.) today issued a subpoena to Dr. Kevin O’Connor, President Joe Biden’s physician, to appear for a deposition on June 27, 2025, as part of the investigation into the cover-up of President Joe Biden’s cognitive decline and potentially unauthorized issuance of sweeping pardons and other executive actions.

 

Chairman Comer recently requested Dr. O’Connor appear voluntarily for a transcribed interview, but he refused. Last Congress, Chairman Comer also requested Dr. O’Connor appear for a transcribed interview to discuss his medical assessments and involvement in the Biden family’s influence peddling racket, but the Biden White House blocked his testimony.

 

“On May 22, 2025, the Committee on Oversight and Government Reform requested that you—because of your role as former Physician to the President for President Joe Biden— appear for a transcribed interview on June 25, 2025, broadly regarding ‘the circumstances surrounding your assessment in February 2024 that former President Biden was ‘a healthy, active, robust 81-year-old male, who remains fit to successfully execute the duties of the Presidency.’’ Among other subjects, the Committee expressed its interest in whether your financial relationship with the Biden family affected your assessment of former President Biden’s physical and mental fitness to fulfill his duties as President. Given your connections with the Biden family, the Committee sought to understand if you contributed to an effort to hide former President Biden’s fitness to serve from the American people. You refused the Committee’s request. However, to advance the Committee’s oversight and legislative responsibilities and interests, your testimony is critical. Accordingly, please see the attached subpoena for testimony at a deposition on June 27, 2025,” wrote Chairman Comer to Dr. O’Connor.

Tesla loses $152 billion in market cap after Musk-Trump spat, biggest hit ever

 

-Shares of Tesla fell 14% on Thursday as President Donald Trump threatened to pull government contracts for CEO Elon Musk’s companies.

-The move dropped the EV maker $152 billion in value, putting it below the $1 trillion benchmark and settling Thursday at $916 billion.

-“Without me, Trump would have lost the election, Dems would control the House and the Republicans would be 51-49 in the Senate,” Musk posted on X.

 

Shares of Tesla

fell 14% on Thursday as President Donald Trump threatened to pull government contracts for CEO Elon Musk’s companies, escalating a war of words over the spending bill.

 

The move dropped the EV maker $152 billion in value, the biggest hit to its market cap ever, putting it below the $1 trillion benchmark and settling Thursday at $916 billion.

 

“Elon was ‘wearing thin,’ I asked him to leave, I took away his EV Mandate that forced everyone to buy Electric Cars that nobody else wanted (that he knew for months I was going to do!), and he just went CRAZY!” Trump wrote on Truth Social.

 

Trump spoke from the Oval Office earlier Thursday and said Musk was upset that EV credits were not included in the bill.

 

“Elon and I had a great relationship. I don’t know if we will anymore,” Trump said in the Oval Office on Thursday. “I was surprised.”

 

“Whatever,” Musk fired back as the president spoke.

 

“Without me, Trump would have lost the election, Dems would control the House and the Republicans would be 51-49 in the Senate,” he posted on X.

 

Musk, the world’s richest man, in recent days has threatened to make lawmakers who vote for the bill face primary elections and called the bill a “disgusting abomination,” marking a significant shift in his comments about the administration.

 

The fall in shares comes after the EV maker saw a 22% rally in May despite weak sales numbers, with Musk wrapping up his time as head of Trump’s so-called Department of Government Efficiency, or DOGE.

 

Shares are down nearly 18% this week as Musk has continued to rail against the budget bill. This year, shares are down nearly 30% and well off the high of $488.54 reached Dec. 18.

 

Since Musk’s special government employee term ended Friday, he’s appeared at odds with the Trump administration and gone on a full assault against the president’s signature tax-cut bill.

 

“One of the things about Elon is when he goes all in, he goes all in,” Walter Isaacson, author of a Musk biography, told CNBC’s “Squawk Box” on Thursday.

 

“He is somebody who’s not exactly calibrated in these things and he is seriously upset,” Isaacson said.

 

Musk, who also runs SpaceX and xAI, posted a stream of attacks against the Trump bill on X Wednesday.

 

NBC News reported that Musk had tried to convince Trump and other GOP members of the administration to change aspects of Trump’s bill that would curtail EV and residential solar tax credits, which generate profits for Tesla.

 

The measure would also impose a new annual $250 fee on EV drivers.

 

Tesla is facing more fundamental problems, with plummeting sales of its electric vehicles in major markets in Europe and a declining brand reputation in the West.

 

Tesla is also under pressure to launch a long-delayed, driverless ride-hailing service this month in Austin, Texas.

 

Musk has said that Tesla is testing driverless vehicles in that market, but its primary competitor Waymo is already operating a major commercial robotaxi service there in partnership with Uber.

 

Isaacson said Thursday that Musk was also annoyed with members of the Trump administration who worked against the nomination of Jared Isaacman as head of space agency NASA.

 

“That, to Musk, was just infuriating because they were doing, they were going after Jared Isaacman … to get at Musk,” Isaacson said Thursday.

 

Isaacman’s nomination was pulled over the weekend.

 

Isaacman led two private spaceflights through Musk’s SpaceX, in 2021 and 2024, commanding crews on trips around the Earth. His payment tech company Shift4 said in financial filings that as of June 30, 2021, it had invested $27.5 million in SpaceX as well.

Breakthrough in search for HIV cure leaves researchers ‘overwhelmed’’

 

A cure for HIV could be a step closer after researchers found a new way to force the virus out of hiding inside human cells.

 

The virus’s ability to conceal itself inside certain white blood cells has been one of the main challenges for scientists looking for a cure. It means there is a reservoir of the HIV in the body, capable of reactivation, that neither the immune system nor drugs can tackle.

 

Now researchers from the Peter Doherty Institute for Infection and Immunity in Melbourne, have demonstrated a way to make the virus visible, paving the way to fully clear it from the body.

 

It is based on mRNA technology, which came to prominence during the Covid-19 pandemic when it was used in vaccines made by Moderna and Pfizer/BioNTech.

 

In a paper published in Nature Communications, the researchers have shown for the first time that mRNA can be delivered into the cells where HIV is hiding, by encasing it in a tiny, specially formulated fat bubble. The mRNA then instructs the cells to reveal the virus.

 

Globally, there are almost 40 million people living with HIV, who must take medication for the rest of their lives in order to suppress the virus and ensure they do not develop symptoms or transmit it. For many it remains deadly, with UNAids figures suggesting one person died of HIV every minute in 2023.

 

It was “previously thought impossible” to deliver mRNA to the type of white blood cell that is home to HIV, said Dr Paula Cevaal, research fellow at the Doherty Institute and co-first author of the study, because those cells did not take up the fat bubbles, or lipid nanoparticles (LNPs), used to carry it.

 

The team have developed a new type of LNP that those cells will accept, known as LNP X. She said: “Our hope is that this new nanoparticle design could be a new pathway to an HIV cure.”

 

When a colleague first presented test results at the lab’s weekly meeting, Cevaal said, they seemed too good to be true.

 

“We sent her back into the lab to repeat it, and she came back the next week with results that were equally good. So we had to believe it. And of course, since then, we’ve repeated it many, many, many more times.

 

“We were overwhelmed by how [much of a] night and day difference it was – from not working before, and then all of a sudden it was working. And all of us were just sitting gasping like, ‘wow’.”

 

Further research will be needed to determine whether revealing the virus is enough to allow the body’s immune system to deal with it, or whether the technology will need to be combined with other therapies to eliminate HIV from the body.

 

The study is laboratory based and was carried out in cells donated by HIV patients. The path to using the technology as part of a cure for patients is long, and would require successful tests in animals followed by safety trials in humans, likely to take years, before efficacy trials could even begin.

 

“In the field of biomedicine, many things eventually don’t make it into the clinic – that is the unfortunate truth; I don’t want to paint a prettier picture than what is the reality,” stressed Cevaal. “But in terms of specifically the field of HIV cure, we have never seen anything close to as good as what we are seeing, in terms of how well we are able to reveal this virus.

 

“So from that point of view, we’re very hopeful that we are also able to see this type of response in an animal, and that we could eventually do this in humans.”

 

Dr Michael Roche of the University of Melbourne and co-senior author of the research, said the discovery could have broader implications beyond HIV, with the relevant white blood cells also involved in other diseases including cancers.

 

Dr Jonathan Stoye, a retrovirologist and emeritus scientist at the Francis Crick Institute, who was not involved in the study, said the approach taken by the Melbourne team appeared be a major advance on existing strategies to force the virus out of hiding, but further studies would be needed to determine how best to kill it after that.

 

He added: “Ultimately, one big unknown remains. Do you need to eliminate the entire reservoir for success or just the major part? If just 10% of the latent reservoir survives will that be sufficient to seed new infection? Only time will tell.

 

“However, that does not detract from the significance of the current study, which represents a major potential advance in delivery of mRNA for therapeutic purposes to blood cells.”

 

Prof Tomáš Hanke of the Jenner Institute, University of Oxford, disputed the idea that getting RNA into white blood cells had been a significant challenge. He said the hope that all cells in the body where HIV was hiding could be reached in this way was “merely a dream”.

GM Invests $888 Million in U.S. Plant for Next-Gen V-8 Production

 

The sixth iteration of GM's small-block V-8 will be built in Buffalo, New York, and the engines will power future full-size trucks and SUVs.

 

-General Motors announced an $888 million investment in the Tonawanda Propulsion plant for the production of a next-generation V-8.

-The Buffalo, New York-based factory will start producing the new V-8s in 2027, which likely aligns with the next-gen Chevy Silverado and GMC Sierra.

-GM says the engines will usher in better performance and efficiency; the new V-8s will also be built at the company's Flint Engine plant.

 

General Motors has heavily invested in electric vehicles. Over the past couple of years, it has launched everything from the affordable Chevy Equinox EV to the luxurious Cadillac Escalade IQ to the Chevy Silverado EV truck. But GM isn't giving up on internal-combustion engines either, as yesterday it announced that it will be investing $888 million in the production of a new generation of V-8 engines.

 

The sixth generation of GM's small-block V-8 is due to start production in 2027 and will continue to be built at the Tonawanda Propulsion plant in Buffalo, New York. The $888 million investment into the facility will bring new machinery and tools for producing the next iteration of the V-8, as well as renovations to the factory, GM said in a statement.

 

Before 2027, the Tonawanda plant will continue assembling the fifth-generation V-8 power plant, made in both 5.3-liter and 6.2-liter guises. The Tonawanda plant also produces the V-8-based 4.3-liter V-6 found in the Chevy Express van, as well as the 6.2-liter V-8 used in the Corvette sports car.

 

General Motors says the next-generation V-8 that will be built at Tonawanda will be used for full-size trucks and SUVs, and the timeline of production starting in 2027 aligns with the expected arrival of a next-generation Silverado and GMC Sierra trucks. GM's next-generation full-size trucks will be followed shortly thereafter by new versions of the Chevy Suburban and Tahoe, GMC Yukon, and Cadillac Escalade, all of which were refreshed for the 2025 model year.

 

GM says it expects the new engines to improve performance while reducing emissions and becoming more efficient. The investment in the Tonawanda facility follows a $500 million investment in the Flint Engine plant from 2023, which is also dedicated to the production of the sixth-generation V-8.

Supreme Court sides with straight woman in decision that makes it easier to win ‘reverse discrimination’ suits

 

The U.S. Supreme Court unanimously ruled in favor of a straight woman who filed a reverse discrimination lawsuit against her employer, making it easier for majority-group plaintiffs to bring such cases. The woman, Marlean Ames, claimed she was passed over for a promotion and later demoted in favor of gay colleagues2.

 

Previously, courts required majority-group plaintiffs to prove "background circumstances" showing a pattern of discrimination against their group, but the Supreme Court rejected this heightened standard. Justice Ketanji Brown Jackson wrote that Title VII of the Civil Rights Act does not impose different requirements based on whether the plaintiff is part of a majority or minority group.

 

The ruling could have significant implications for workplace discrimination lawsuits, particularly as debates over diversity, equity, and inclusion (DEI) efforts continue.

Silver jumps to highest level in 13 years, following gold’s 2025 rally

 

The price of silver moved sharply higher Thursday morning and hit its highest level in more than a decade.

 

Silver futures

rose as high as $36.27 per troy ounce on Thursday, notching the highest price for the metal since early 2012. Silver futures were last up more than 3% on the day at $35.81 per troy ounce.

 

Silver has been a high-performing asset in 2025 and is now up more than 20% year to date. That is still lagging the move in gold

, however, which has jumped about 28%. The price of gold was down slightly on Thursday, meaning silver’s rally closed some of the gap between the two.

 

Silver has industrial uses, including in solar panels, and is also seen by some investors as a defensive precious metal, similar to gold. A recent survey from the Silver Institute estimated that the supply of silver was about 15% lower than demand in 2024 and projected another deficit in 2025.

Homeland Security details shocking abuse of migrant children; adults impregnated children

 

The Biden administration placed some illegal immigrant children with sponsors who got them pregnant, the Homeland Security Department said Thursday.

 

In other cases, minors who showed up at the border without parents were sent to live with adults who possessed child pornography, had serious criminal records or forced the children into labor.

 

Hundreds of thousands of these unaccompanied alien children surged into the U.S. as part of the Biden border breakdown. The administration struggled to process them. Facing overcrowded and dangerous conditions, it cut corners to push the children out of detention as quickly as possible, leaving some in unsafe placements, the government now says.

 

“Children’s safety and security is nonnegotiable,” said Laszlo Baksay, a spokesperson at U.S. Immigration and Customs Enforcement. “The previous administration’s failure to implement meaningful safeguards has allowed vulnerable kids to fall into the hands of criminals.”

 

Homeland Security Investigations, a division of ICE, has spent the past few months trying to check up on the children. Thursday’s findings grew out of that effort.

 

Some of the children were living in what ICE described as “neglect.” Others were with sponsors who had criminal records that included assault, drug trafficking, prostitution and attempted murder.

 

In what the agency called the “most disturbing cases,” girls were pregnant with children fathered by their “alleged sponsors.”

 

Unaccompanied alien children have long been among the toughest immigration cases, creating difficulties for all involved.

 

The children face horrific dangers en route to the U.S. Once in custody, they are supposed to be placed with sponsors who can look after them while they fight for permanent legal status.

 

Because of the sheer number of sponsors during the Biden administration, which in some early months topped 18,000, the government couldn’t vet sponsors properly under the rules inherited from the previous Trump administration.

 

The Health and Human Services Department loosened the requirements, but analysts said the result was more dangerous placements.

 

Federal watchdogs previously said the government had lost track of tens of thousands of children and failed to keep tabs on hundreds of thousands more.

 

The Trump administration vowed to track down the children it could, but welfare checks have been tricky.

 

Jarrod Sadulski, a child trafficking expert who has testified to Congress on these issues, said investigators made 100,000 attempts but located only about 5,000 children, or a rate of just 5%.

 

They identified more than two dozen cases that showed signs of trafficking.

 

Mr. Sadulski said HHS also ignored more than 65,000 calls to its UAC abuse hotline.

 

Sen. Charles E. Grassley, Iowa Republican, said last week that 7,300 of those calls involved accusations of trafficking and nearly 1,700 alleged fraud.

 

Mr. Sadulski said people could sign up as sponsors by identifying themselves with as little as a texted photo of a driver’s license.

 

That meant people with no connection to the children could pose as parents or other relatives and claim custody.

 

In one criminal case brought this year, authorities charged an illegal immigrant from Guatemala with fraudulently obtaining sponsorship of an unaccompanied alien child. He had submitted a badly photoshopped picture of himself and a woman to claim he was the child’s father, investigators said.

 

In a second instance, the man tried to claim sponsorship of another child with an ID that didn’t belong to him, investigators said.

 

HHS approved the first application but managed to deny the second one.

 

Federal prosecutors in New Mexico, meanwhile, brought charges against a 35-year-old man who they said paid to smuggle a 17-year-old girl to his home in Virginia.

 

Luis Alonso Argueta-Diaz told federal agents he was paying to have the girl come to a “safe place” and be a nanny for his three children, according to court documents. He admitted to paying $2,000 to the girl’s mother in Honduras. The girl said her total smuggling fee was $20,000, most of which was still outstanding.

 

Even as the welfare checks unveil troubling cases, immigrant rights groups complain that the stories are scaring migrants.

 

El Pais reported last month that more than 100 unaccompanied alien children had been displaced because of the checks.

 

“These welfare checks are planting fear, panic, and confusion among children and family members around the country,” Jason Boyd, vice president of federal policy for Kids in Need of Defense, told the news outlet. “Numerous minors have been subjected to deportation proceedings after such checks, which are by definition a tactic of migratory control.”

 

ICE, in announcing its findings Thursday, said immigration enforcement isn’t the purpose of the checks but said if agents or officers come across someone in the U.S. illegally, they will take them into custody.

 

The Trump administration has moved to tighten the rules on sponsorship to protect children. That includes requiring an unexpired authentic identification, which appears to be blocking many illegal immigrants from claiming sponsorship of their own children.

 

Just 45 minors were released to sponsors in April, down from more than 5,000 each month in late 2024.

 

A federal judge is deciding whether to block the Trump administration’s changes.

US engineers create self-healing robot skin that detects, seals, and resets

 

Nebraska engineers built a soft robot muscle that mimics human healing, using heat and liquid metal to fix and forget damage.

 

While not as dramatic as that film, engineers from the University of Nebraska–Lincoln have developed a promising new soft robotics system that can detect and repair its own damage.

 

This autonomous, self-healing artificial muscle mimics how human and plant skin react to injury.

 

The work, led by Husker engineer Eric Markvicka and graduate students Ethan Krings and Patrick McManigal, could reshape how electronics and machines handle damage.

 

Markvicka’s team focused on a longstanding gap in biomimicry: the ability to sense and heal damage like living organisms do.

 

“In our community, there is a huge push toward replicating traditional rigid systems using soft materials, and a huge movement toward biomimicry,” Markvicka said.

 

“While we’ve been able to create stretchable electronics and actuators that are soft and conformal, they often don’t mimic biology in their ability to respond to damage and then initiate self-repair.”

 

To solve this, the team designed a three-layer artificial muscle. The bottom layer is a soft electronic skin made of silicone embedded with liquid metal microdroplets, which detects and locates damage.

 

The middle layer consists of a stiff thermoplastic elastomer that enables self-healing.

 

On top, the actuation layer moves the muscle when it’s pressurized with water.

 

The artificial muscle can detect where damage occurs, then kickstart a healing process without help from humans.

 

It works by running five monitoring currents through the electronic skin. When damaged, this skin creates a new electrical path. The system recognizes this path and increases current through it, turning the damaged area into a Joule heater.

 

The resulting heat melts and reseals the middle layer, closing the puncture.

 

Later, the system must be reset by removing the damage footprint from the bottom layer.

 

To reset the system, the team used electromigration, which is usually a problem in electronics.

 

Electromigration shifts metal atoms when current flows through them, often leading to failure in circuits.

 

Markvicka’s team harnessed this failure mode to intentionally erase the damage path, making the system reusable.

 

“Electromigration is generally seen as a huge negative,” Markvicka said.

 

“It’s one of the bottlenecks that has prevented the miniaturization of electronics. We use it in a unique and really positive way here. Instead of trying to prevent it from happening, we are, for the first time, harnessing it to erase traces that we used to think were permanent.”

 

The implications of this self-repairing tech stretch far beyond the lab.

 

In agriculture-heavy states like Nebraska, robots often get damaged by thorns, twigs, or plastic. Self-healing systems could extend their lifespans. Wearable medical devices could also benefit, surviving the rigors of daily use.

 

More broadly, reducing electronic waste could help protect environmental and human health.

 

“If we can begin to create materials that are able to passably and autonomously detect when damage has happened, and then initiate these self-repair mechanisms, it would really be transformative,” Markvicka said.

 

Their findings were recently presented at the IEEE International Conference on Robotics and Automation in Atlanta, Georgia.

 

It earned recognition as one of only 39 Best Paper Award finalists out of 1,606 submissions.

Black Hawk Down was a great movie but I was always pissed that the humvees with the turret on top didn't offer a shield to protect the guy manning it. Basically those guys who went up all got killed and deserve a Medal of Honor. Why not use something like picrel with a surrounding pod around the turret to protect the gunner? Gunner's Lives Matter.
