House Speaker Mike Johnson's chief of staff Hayden Haynes was arrested late Tuesday night for drunken driving after President Donald Trump's speech to a joint session of Congress, NBC News reported Wednesday.

Haynes has worked for Johnson as his chief of staff since 2017, and was promoted to run the speaker's office after Johnson was elected to the top job in 2023. He has also worked for former Louisiana GOP Sen. David Vitter from 2009 to 2016.

Police sources told the outlet that Haynes allegedly backed his car into another vehicle at the Capitol, prompting the arrest and a citation to appear in court. The incident occurred shortly before midnight.

“A driver backed into a parked vehicle last night around 11:40 p.m.," the U.S. Capitol Police said in a statement. "We responded and arrested them for DUI.”

Johnson's office has confirmed that it was notified of the incident, and said that the speaker still has "full faith and confidence" in his aide's ability to run his office.

“The Speaker is aware of the encounter that occurred last night involving his Chief of Staff and the Capitol Police," Johnson spokesperson Taylor Haulsee told NBC News. "The Speaker has known and worked closely with Hayden for nearly a decade and trusted him to serve as his Chief of Staff for his entire tenure in Congress. 

"Because of this and Hayden’s esteemed reputation among Members and staff alike, the Speaker has full faith and confidence in Hayden’s ability to lead the Speaker’s office," he added.
