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.

The FBI has searched the Maryland home and Washington office of ex-Trump national security adviser John Bolton as part of an investigation into the handling of classified information.

Sources familiar with the matter told ABC News that the search, carried out by the FBI, was related to allegations that Bolton is in possession of classified records.
