GREENBELT, Md. — John Bolton, the former national security adviser to President Donald Trump who became one of his most outspoken critics, pleaded not guilty Friday to charges he had mishandled classified information while a top White House aide.

Bolton, in a navy suit and red tie, appeared in U.S. District Court in Greenbelt, Maryland, a day after he was indicted by a grand jury on 18 counts of either transmitting or illegally retaining classified information. Much of that was in the form of notes about his day-to-day work for Trump in 2018 and 2019.

The magistrate judge, Timothy J. Sullivan, released Bolton on the condition that he remain in the continental United States. Like many criminal defendants, Bolton was required to turn over his passport.
