GREENBELT, Md. — John Bolton, once a close advisor to President Trump and now an adversary, turned himself in to authorities on Friday morning following accusations of improperly handling classified information.

Bolton made his way to the federal courthouse in Greenbelt, Md., around 8:30 a.m., where he was observed entering the U.S. Marshal’s office accompanied by his legal team. He is anticipated to have his initial court hearing later in the day.

The previous day, a federal grand jury indicted Bolton on 18 counts, marking him as the third prominent Trump critic to face recent charges from the Justice Department.

According to prosecutors, he allegedly shared over a thousand pages of personal notes, detailing his experiences as Trump’s national security adviser, with two family members and retained these documents at his Maryland home after his tenure ended.

In response to the allegations, Bolton issued a statement claiming to be the “latest target” in what he describes as Trump’s retaliatory efforts against political opponents. He asserted his lifelong commitment to U.S. foreign policy and national security, emphasizing that he would “never compromise those principles.”

His lawyer, prominent Washington attorney Abbe Lowell, said that keeping diaries “is not a crime.”

Lowell also represents New York Attorney General Letitia James (D), another Trump adversary who was charged last week with bank fraud in connection with her purchase of a Virginia home.

Former FBI Director James Comey also faces charges he lied in 2020 congressional testimony.

They both have denied wrongdoing.
