The raid on Bolton's home was part of an investigation into the handling of classified documents according to The Associated Press.

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.

As FBI agents on Friday searched the home and office of John Bolton, once a top adviser to the president, Donald Trump didn't hold back, telling reporters: "I'm not a fan of John Bolton. He's a real sort of a lowlife."
