The FBI is searching the Maryland home of former Trump administration national security adviser John Bolton as part of an investigation into the handling of classified documents.

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.

An investigation seeks to determine whether Mr. Bolton illegally shared or possessed classified information, according to two people familiar with the case.

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.

But no one can say definitively whether today’s raid is due to Bolton’s status as critic, Bolton’s bad judgment or malfeasance, or nothing at all.
