CIA Director John Ratcliffe provided FBI Director Patel the intelligence that was the basis of the search warrant, a source familiar with the matter told NBC News.

The FBI was searching the home of former national security adviser John Bolton, who has become a critic of President Trump, according to news reports.

Trump, during that first term, was churning through national security advisers with regularity, and Bolton jumped from his role as a Fox News analyst to the White House in March of 2018 after promising Trump “he wouldn’t start any wars” if he was selected, CNN reported at the time.
