Former National Security Adviser John Bolton has reached a plea agreement with the U.S. Department of Justice and is expected to plead guilty to one count of retaining classified information. The agreement would resolve a criminal case that originally included 18 charges alleging Bolton improperly retained and shared sensitive national security materials, including diary-style notes from his time in government. Under the reported deal, Bolton would pay a $2.25 million fine and could avoid prison time, although the final sentence will be determined by a federal judge.
