Much of the federal government officially shut down early Saturday morning after Senate Democrats, showing remarkable solidarity in the face of a clear political danger, blocked consideration of a stopgap spending measure to keep the government operating.
But senators from both parties were scrambling for a new deal to reopen the government quickly, possibly just hours after the midnight deadline passed.
With just 50 senators voting in favor, Senate Republican leaders fell well short of the 60 votes necessary to proceed on the spending measure, which had passed the House on Thursday. As the clock ticked toward midnight, when funding for the government was set to expire, senators huddled on the floor of the crowded Senate chamber, searching for some way forward.
But even if the Senate had adopted such a bill, it would also have had to pass the House, and lawmakers simply ran out of time. The government shutdown was one year to the day after President Trump took office.
“Senate Democrats own the Schumer Shutdown,” the White House press secretary, Sarah Huckabee Sanders, said in a statement. “Tonight, they put politics above our national security, military families, and our country’s ability to serve all Americans.”
Democrats countered that Republicans were responsible for the management of a government in their control.
“A Republican president occupies the White House, and Republicans hold the majority in both the House of Representatives and the Senate,” said Representative Nita Lowey, Democrat of New York. “It is outrageous that, even with unified control of government, the majority could not chart a course toward keeping the government open, the most basic responsibility of Congress.”
The Senate’s vote, late Friday night, came after a day of budget brinkmanship in Washington that included a last-minute negotiating session between Mr. Trump and Senator Chuck Schumer of New York, the Democratic leader. The 90-minute meeting produced progress, both men said, but no deal. Just hours later, it appeared to collapse.
