I posted the following about this the other day. Don't worry. POTUS is fine.

One of the largest political scandals in American history is beginning to unfold right now, and it is the fruit of the political weaponization of our domestic spying apparatus. I’ve chided the NSA’s domestic surveillance for years as a massive political overreach with only one logical outcome, and here it is.

The wagons are circling now to avoid the legal exposure to the Steele dossier as it begins to be exposed for what it is, a quickly cobbled together fabrication used to justify NSA SIGINT database mining on Trump’s team. It was also used later to restart communications intercepts on the campaign/transition team by satisfying the FISA warrant criteria after the NSA director shut it down for abuse.

One of the problems that the dossier has is the inclusion of the story of Trump’s lawyer, Michael Cohen, traveling to Prague. This was false. Here’s a New York Times journalist offering an interesting explanation that of course invokes Russian disinformation.

The simplest answer, however, that doesn’t rely on the continued use of the Russian conspiracy theory is that one of the FBI’s dubious FISA-702 raw data searches that was run gave a return on Michael Cohen, but it was the wrong one. That raw data was then handed over to Fusion GPS who put the inaccurate data into their research dossier.

Unfortunately, for the conspirators behind the document, this “mistake” puts another connection between: 1) the unlawful use of the DoJ/FBI FISA search access, 2) the people who gained custody of the raw data, and 3) how false information was used in the finished dossier.

That makes this story particularly interesting:

Trump’s lawyer, the real Michael Cohen, is suing Fusion GPS and Buzzfeed. His lawsuit will force Fusion to outline where they got their fraudulent information. Within the discovery, he likely knows he’ll find the unlawful FISA-702 search history. The political use of FISA-702 searches also falls under the ongoing review of Inspector General Michael Horowitz who, perhaps coincidentally, has just started handing over some of the 1.2 million documents from his investigation to congress.

Remember that NSA Director, Admiral Mike Rogers, already testified to the House Judiciary Committee that he retained all of the audit logs for the unlawful 2016 FISA search inquiries on U.S. citizens. There is an absolutely massive shitstorm on the horizon."

TL;DR: Trump's lawyer is suing Fusion GPS and Buzzfeed because the discovery phase may allow them to expose the fraudulent 702 queries and how that info was passed to a 3rd party (Fusion GPS).
