The Federal Bureau of Investigation confiscated multiple electronics and files from former Trump national security adviser John Bolton’s home and office during raids late last month.

Bolton is the subject of an investigation involving the release of classified information. During the raids on his home and office on Aug. 22, the FBI took two iPhones, a white binder labeled “statements and reflections to allied strikes, “typed documents in folders labeled ‘Trump I – IV,’” four boxes of “printed daily activities,” one hard drive, two Sandisk USB drives and three Dell computers, according to an inventory list and warrant made public by the Justice Department on Thursday.

According to the warrant, authorities are investigating Bolton for possible violation of 18 U.S. Code § 793 — gathering, transmitting or losing defense information; and 18 U.S. Code § 1924 — unauthorized removal and retention of classified documents or material.

During President Donald Trump’s first administration, the Justice Department started to investigate Bolton because of his book “The Room Where It Happened: A White House Memoir,” which shed light on his time working for Trump. The DOJ tried to stop the book from being released. While the investigation ended under former President Joe Biden, CNN reported that it has actually resumed.
