Bolton, who served for 17 months in the national security adviser role in Donald Trump’s first term, has since turned into a fierce critic of the president.

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 raided former national security adviser John Bolton’s home early Friday morning. Agents conducted the operation at Bolton’s Maryland residence as part of a high-profile national security investigation ordered by FBI Director Kash Patel.
