If you didn't think Mueller was working with Trump or were not sure this article will seal the deal:
..Mueller’s remarks that day soared in a way unlike almost any other speech he'd deliver.
“There are those who say that time heals all wounds. But you know that not to be true. At its best, time may dull the deepest wounds; it cannot make them disappear,” Mueller told the assembled mourners. “Yet out of the darkness of this day comes a ray of light. The light of unity, of friendship, and of comfort from those who once were strangers and who are now bonded together by a terrible moment in time.
None of his cases in Washington, though, would affect him as much as the bombing of Pan Am 103.
…1989 and 1990, Robert Mueller arrived at Main Justice; the final objects of the Lockerbie search wouldn’t be found until the "'spring of 1990, just months before Mueller took over as assistant attorney general of the criminal division in September.'''
The Justice Department that year was undergoing a series of leadership changes; the deputy attorney general, William Barr, became acting attorney general mid-year (Earlier this month Barr was nominated by President Trump to become attorney general once again.)
…For Mueller, the case became personal; he met with victims’ families
“However, the primary target of this act of terrorism was the United States. The majority of the victims were Americans, and the Pan American aircraft was targeted precisely because it was of United States registry.”
…To make the stunning announcement against Libya, Mueller joined FBI Director William Sessions, DC US Attorney Jay Stephens, and Attorney General William Barr.
“We charge that two Libyan officials, acting as operatives of the Libyan intelligence agency, along with other co-conspirators, planted and detonated the bomb that destroyed Pan Am 103,” Barr said. “I have just telephoned some of the families of those murdered on Pan Am 103..
At the press conference, Barr listed a long set of names to thank—the first one he singled out was Mueller’s. Then, he continued- We will not rest until all those responsible are brought to justice. We have no higher priority.”
…The trial began in May 2000. For nine months, the court heard testimony from around the world. In what many observers saw as a political verdict, Al Megrahi was found guilty
That day, Mueller awoke early and joined with victims’ families and other officials in Washington… As he told the media, “The United States remains vigilant in its pursuit to bring to justice any other individuals who may have been involved in the conspiracy to bring down Pan Am Flight 103.”
Just months after that 20th anniversary ceremony with Mueller at Arlington National Cemetery, in the summer of 2009, Scotland released a terminally ill Megrahi from prison on “compassionate grounds.”
The idea that Megrahi could walk out of prison on “compassionate” ground made a mockery of everything that Mueller had dedicated his life to fighting and doing. Amid a series of tepid official condemnations—President Obama labeled it “highly objectionable”
Mueller began “Your decision to release Megrahi causes me to abandon that practice in this case. I do so because I am familiar with the facts, and the law, having been the Assistant Attorney General in charge of the investigation and indictment of Megrahi in 1991. And I do so because I am outraged at your decision, blithely defended on the grounds of ‘compassion.’”
“Your action in releasing Megrahi is as inexplicable as it is detrimental to the cause of justice. Indeed your action makes a mockery of the rule of law. Your action gives comfort to terrorists around the world,” Mueller wrote. “You could not have spent much time with the families, certainly not as much time as others involved in the investigation and prosecution-

And who let Megrahi walk???
Barack Hussein Roman Obama:
The document, acquired by a well-placed US source, threatens to undermine US President Barack Obama's claim last week that all Americans were "surprised, disappointed and angry" to learn of Megrahi's release.
The US has tried to keep the letter secret, refusing to give permission to the Scottish authorities to publish it…
"Nevertheless, if Scottish authorities come to the conclusion that Megrahi must be released from Scottish custody, the US position is that conditional release on compassionate grounds would be a far preferable alternative to prisoner transfer, which we strongly oppose."
The Sunday Times revealed this month that Megrahi's doctors thought he could live for another decade.
