WATCH: Senate convenes as the House passes funding bill to avoid government shutdown

WASHINGTON (AP) — With hours to go before the midnight deadline to fund the government, the House on Saturday swiftly approved a temporary funding bill to keep federal agencies open. The measure now goes to the Senate, which also is meeting Saturday.

“Congress has only one option to avoid a shutdown — bipartisanship,” said Senate Majority Leader Chuck Schumer, D-N.Y.

Senate Republican leader Mitch McConnell of Kentucky echoed the sentiment, warning his own hard-right colleagues there is nothing to gain by shutting down the federal government.

“It heaps unnecessary hardships on the American people, as well as the brave men and women who keep us safe,” McConnell said.

Across the Capitol, McCarthy dropped demands for steep spending cuts and relied on Democratic votes for passage to send the package to the Senate.

The new approach would leave behind aid to Ukraine, a White House priority opposed by a growing number of GOP lawmakers, but the plan would increase federal disaster assistance by $16 billion, meeting President Joe Biden’s full request. The package was approved 335-91, with most Republicans and almost all Democrats supporting.

“We’re going to do our job,” McCarthy said before the House vote. “We’re going to be adults in the room. And we’re going to keep government open.”

The House measure would fund government at current 2023 levels through Nov. 17, moving closer to the bipartisan approach in the Senate. But the Senate package would have added $6 billion for Ukraine to fight the war against Russia and $6 billion for U.S. disaster relief.

Both chambers came to a standstill as lawmakers assessed their options, some decrying the loss of Ukraine aid.

For the House package to be approved, McCarthy, R-Calif., was forced to rely on Democrats because the speaker’s hard-right flank has said it will oppose any short-term funding measure, denying him the votes needed from his slim majority. It’s a move that risks his job amid calls for his ouster.

After leaving his right-flank behind, McCarthy is almost certain to be facing a motion to try to remove from office, though it is not at all certain there would be enough votes to topple the speaker. Most Republicans voted for the package Saturday while 90 opposed.

“If somebody wants to remove me because I want to be the adult in the room, go ahead and try,” McCarthy said of the threat to oust him. “But I think this country is too important.”
