(ASSOCIATED PRESS) The Senate approached a key test vote Friday afternoon as lawmakers worked to avoid a partial government shutdown, with Democrats confronting two painful options: allowing passage of a bill they believe gives President Donald Trump vast discretion on spending decisions or voting no and letting a funding lapse ensue.

At least eight Democrats will need to join with Republicans to get the bill to a 60-vote threshold and advance it.

Senate Democratic leader Chuck Schumer gave members of his caucus days to vent their frustration about the options before them, but abruptly switched course and made clear on the eve of voting that he will not allow a government shutdown. His move outraged many in the party who want to fight the Trump agenda, but gives senators room to side with Republicans and allow the continuing resolution, often described as a CR, to advance.

In a rare move, the House Democratic leadership, which essentially held the line against the bill in their chamber, issued a scathing rejoinder, warning against caving to Trump, billionaire Elon Musk and the Republican agenda marching forward in Congress.

“House Democrats will not be complicit,” wrote House Democratic Leader Hakeem Jeffries, House Democratic Whip Katherine Clark and House Democratic Caucus Chair Pete Aguilar in a joint statement from the party’s annual issues conference retreat, where frustrations were boiling over.

“We remain strongly opposed to the partisan spending bill under consideration in the Senate.”

But early Friday, Schumer picked up one unexpected nod of support — from Trump himself, who just a day earlier was gearing up to blame Democrats for any shutdown.

“Congratulations to Chuck Schumer for doing the right thing — Took ‘guts’ and courage!” the president posted on his social media account.

Schumer has acknowledged the difficult choice he faced, but insisted Democrats would not allow a government shutdown and warned of the havoc Trump and Musk could bring if federal offices shuttered.

“A shutdown will allow DOGE to shift into overdrive,” Schumer said, referring to the Musk-led Department of Government Efficiency. “Donald Trump and Elon Musk would be free to destroy vital government services at a much faster rate.”

Congress has been unable to pass the annual appropriations bills designed to fund the government, so they've resorted to passing short-term extensions instead. The legislation before the Senate is the third such continuing resolution for the current fiscal year, now nearly half over.

The legislation would fund the federal government through the end of September. It would trim non-defense spending by about $13 billion from the previous year and increase defense spending by about $6 billion, which are marginal changes when talking about a topline spending level of nearly $1.7 trillion.

The Republican-led House passed the spending bill on Tuesday and then adjourned. The move left senators with a decision to either take it or leave it. And while Democrats have been pushing for a vote on a fourth short-term extension, GOP leadership made clear that option was a non-starter.

Senate Majority Leader John Thune, R-S.D., and others made the case that any blame for a shutdown would fall squarely on Democrats.

“Democrats need to decide if they're going to support funding legislation that came over from the House, or if they're going to shut down the government,” Thune said.

Progressive groups urged Democratic lawmakers to insist on the 30-day extension and oppose the spending bill, saying business as usual must not continue.
