John Bolton has pleaded not guilty to charges accusing the former President Donald Trump national security adviser-turned critic of emailing classified information to family members and keeping top secret documents at his Maryland home.

Bolton did not comment to reporters as he entered the courthouse in Greenbelt, Maryland, where he made his initial appearance before a judge on the 18-count indictment brought against him on Thursday.
