Jamaal Bowman is facing a formal investigation into the incident
Republicans are demanding the expulsion of a Left-wing Democrat congressman who triggered a fire alarm delaying a critical vote to head off a government shutdown.
Jamaal Bowman is facing a formal investigation into the incident by the House Administration Committee, while Republican congresswoman Nicole Malliotakis has drafted a resolution demanding the 47-year-old representative from New York be thrown out of Capitol Hill.
The furore centres on an incident shortly after noon on Saturday as members of Congress were preparing to vote on the stopgap measure.
Mr Bowman triggered the alarm by trying to use an emergency exit, causing the house to be evacuated and delaying the vote by an hour.
