The reported incident occurred shortly before Trump announced on Wednesday Ambassador to Germany Richard Grenell would take over from Maguire as the acting intelligence chief.

Trump decided against nominating Maguire for the post on a permanent basis after learning a member of his staff, Shelby Pierson, gave a classified briefing last Thursday to the House Intelligence Committee regarding election security, the newspaper reported, citing people familiar with the matter.

Trump was furious and held Maguire personally responsible when the two next met, the Post reported, resulting in a “dressing down” by the president and which served as “the catalyst” for Trump ultimately opting to appoint Grenell.

A committee official told the Post the briefing concerned “election security and foreign interference in the run-up to the 2020 election,” speaking on condition of anonymity.

“Members on both sides participated, including Ranking Member [Devin] Nunes [R-Calif.], and heard the exact same briefing from experts across the Intelligence Community,” the committee official said. “No special or separate briefing was provided to one side or to any single member, including the chairman.”
