Government shutdown updates: Biden signs stopgap funding measure

The Senate is not voting, as the clock is ticking toward a government shutdown.

Earlier Saturdayday the House passed its short-term funding bill, which funds the government for 45 days and provides disaster aid. But the Senate has been in recess for a few hours now and is running out of time to pass the House bill before the midnight deadline.

All Senators in the chamber have to agree to hold a vote tonight. Right now, one is standing in the way.

Sen. Michael Bennet, D-Colo., is demanding that Senate leadership assure him they'll hold a vote at some point soon on additional funding for Ukraine, which the House stripped out of the bill. If they can't assure him, he might block the Senate from holding a vote Saturday night.

It's not yet clear what the way out of this is. Sources are generally optimistic they'll find a work around before the clock strikes midnight, but it could be a nail-biter.

Speaking to reporters after the House vote, House Speaker Kevin McCarthy, R-Calif., struck a bipartisan tone -- and told those members who want to oust him because he worked with Democrats to "bring it."

"It's all right if Republicans and Democrats joined together to do what is right," McCarthy said. "If somebody wants to make a motion against me, bring it. There has to be an adult in the room."

Asked by ABC News if he was satisfied with the final tally, which had largely Democratic votes, McCarthy said: "I think at the end of the day, we kept the government open, kept paying our troops to finish the job we have to get done."

McCarthy said he had "tried every possible way listening to every single person in the conference."

"I don't want to be a part of that team,” he continued, referring to the far-right members of the Republican party. "I want to be part of a conservative group that wants to get things done."

Rep. Jamaal Bowman, D-NY, "regrets" triggering a building alarm in the Cannon House Office Building earlier Saturday, a spokesperson said.

"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, Emma Simon, said in a statement to ABC News.

The fire alarm was triggered at 12:05 p.m. on the second floor of the building, according to a U.S. Capitol Police spokesperson. The building was evacuated and reopened after officers determined there was no threat.

"An investigation into what happened and why continues," the Capitol Police spokesperson said.

The alarm went off as Democrats were scrambling to make it back to the Capitol to vote and buy themselves more time to review the GOP bill.

According to a White House official, the bill passed by the House of Representatives keeps the government open at a higher funding levels than the Senate bill and includes disaster relief and FAA authorization.

The White House expects House Speaker Kevin McCarthy -- who has stated his support for funding to support Ukraine -- to bring a separate bill to the floor "shortly."
