John Demers

John Charles Demers (born September 21, 1971) is an American attorney who served as the assistant attorney general of the National Security Division. An appointee of President Donald Trump, he served under both, President Donald Trump and President Joe Biden. John Demers also served as acting United States Attorney General for a few hours following the resignation of the previous acting United States Attorney General Jeffrey Rosen at noon on January 20, 2021, until President Joe Biden signed an executive order naming Deputy Assistant Attorney General for Human Resources and Administration Monty Wilkinson as acting United States Attorney General later that day.Prior to Demers's departure, he was the longest-serving Senate-confirmed official from the Trump administration, that was retained for the Biden administration. Demers's long-planned departure from the Justice Department garnered attention when the Trump administration data seizure became publicly known in June 2021, which happened to coincide with his departure. Though Demers asked to leave immediately, the Biden administration asked him to remain until the end of June. Demers was succeeded by Matthew Olsen. At the end of June, with Olsen not yet confirmed, Demers left the Justice Department and was replaced on an acting basis by acting acting Brooklyn U.S. Attorney Mark Lesko.
