Rep. Jamaal Bowman pulled a fire alarm in the Cannon House Office Building on Saturday morning, shortly before the House was scheduled to vote on a government funding bill, which the New York Democrat said was an accident.
The incident was first revealed by House Administration Committee Chairman Bryan Steil, a Republican from Wisconsin.
"Rep (Jamaal) Bowman pulled a fire alarm in Cannon this morning. An investigation into why it was pulled is underway," Steil said in a statement.
Bowman's office said it was an accident.
"Congressman Bowman did not realize he would trigger a building alarm as he was rushing to make an urgent vote. The Congressman regrets any confusion," his spokesperson said.
Leadership in both parties was informed of the situation once Bowman was identified in security footage, a source familiar said.
Rep. Lisa McClain, a Michigan Republican and member of the GOP leadership team, told CNN she is circulating a resolution to censure Bowman over the incident. She said she already has co-sponsors.
