John Bolton, 77, former national security adviser to President Donald Trump, pleaded guilty to a single federal charge of unlawfully retaining classified national defense information on June 26, 2026, in Maryland federal court [1, 2, 3, 4, 5, 6, 7, 8, 9, 10].

Bolton dismissed the earlier 18 criminal counts against him by entering the guilty plea to the one charge [1, 3, 4, 5, 6, 9, 10]. He admitted his guilt in court, saying, "I did your honor" and expressing remorse by adding, "I’m sorry for it" to the judge [1, 5, 10].

The classified materials included over 1,000 pages of diary-like notes and detailed summaries from national security briefings and meetings with senior officials and foreign leaders. Bolton gathered these as source material for his 2020 book, The Room Where It Happened [1, 11, 4, 5, 8, 9, 10]. During 2018 and 2019, he sent many of these classified pages via personal email to family members [5, 9, 10].

Prosecutors said Bolton knew the harm mishandling such sensitive information could cause to national security but broke the law regardless. US Attorney Kelly Hayes said, "He also knew the damage to national security that could be caused by mishandling that sensitive information. Nevertheless, as Mr. Bolton just admitted, he put our national security at grave risk in violation of the law" [1, 5].

Bolton faces up to five years in prison and has agreed to pay a $2.25 million fine as part of a plea deal. The agreement also requires him to perform up to 100 hours of community service related to classified information disclosures and join debriefings with Justice Department and intelligence officials [1, 12, 11, 4, 5, 6, 9, 10]. His lawyer Abbe Lowell said Bolton "took responsibility for a mistake he made, thereby saving the government resources to pursue a case that could expose additional sensitive information" [1]. One source indicated Bolton will forfeit his government pension as well [5].

Bolton's personal email account was reportedly hacked by a party believed linked to Iran, fuelling concerns about possible exposure of classified materials [5, 9, 10].

The Department of Justice began investigating Bolton before former President Trump resumed office in 2025, with support from career prosecutors [11, 8, 9]. Bolton was fired from his White House role in 2019 due to policy disagreements [1, 11, 9, 10].

Bolton was indicted in October 2025 on the original 18 counts related to mishandling classified information following an FBI raid on his home and office in August 2025 [1, 11, 7, 9].

His sentencing hearing is scheduled for October 28, 2026, before US District Judge Theodore D. Chuang in Greenbelt, Maryland [1, 4, 5, 9].
