WASHINGTON - (AP) -- Facing a midnight deadline to avoid a partial government shutdown, President Donald Trump said Friday a closure would drag on "for a very long time" and he tried to lay blame on congressional Democrats if there's no deal over his demand for U.S.-Mexico border wall money.
Only a week ago, Trump said he would be "proud" to shut down the government, which Republicans now control, in the name of border security. "I will take the mantle. I will be the one to shut it down," he asserted.
But with the hours dwindling before the midnight deadline, Trump sought to reframe the debate and make Democrats the holdouts to settling an impasse that threatens hundreds of thousands of federal workers on the eve of the end-of-the-year holidays.
And he exhorted the Senate's Republican leader to corral enough Democratic votes to send a House-passed plan to the White House, even though the measure is almost certain to be rejected in the Senate.
"Senator Mitch McConnell should fight for the Wall and Border Security as hard as he fought for anything. He will need Democrat votes, but as shown in the House, good things happen. If enough Dems don't vote, it will be a Democrat Shutdown!" he tweeted.
Trump also encouraged McConnell, R-Ky., to change the Senate's rules in order to pass the spending bill, lowering the threshold for ending debate on legislation from 60 votes to 51, as it currently stands for judicial appointments.
"Mitch, use the Nuclear Option and get it done! Our Country is counting on you!," Trump tweeted, though McConnell has previously resisted the rules change.
The Senate has been called back into session to consider a package approved by House Republicans late Thursday that includes the $5.7 billion Trump wants for the border with Mexico.
Senators had passed their own bipartisan bill earlier in the week to keep the government running, with border security at existing levels, $1.3 billion, but no money for the wall. Both bills would extend government funding through Feb. 8.
The White House said Trump would not travel to Florida on Friday as planned for the Christmas holiday if the government were shutting down.
More than 800,000 federal workers will be facing furloughs or forced to work without pay if a resolution is not reached before funding expires at midnight Friday.
At issue is funding for nine of 15 Cabinet-level departments and dozens of agencies, including the departments of Homeland Security, Transportation, Interior, Agriculture, State and Justice, as well as national parks and forests.
Many agencies, including the Pentagon and the departments of Veterans Affairs and Health and Human Services, are funded for the year and would continue to operate as usual. The U.S. Postal Service, busy delivering packages for the holiday season, would not be affected by any government shutdown because it's an independent agency.
The shutdown crisis could be one of the final acts of the House GOP majority before relinquishing control to Democrats in January.
Congress had been on track to fund the government but lurched when Trump, after a rare lashing from conservative supporters, declared Thursday he would not sign a bill without the funding. Conservatives want to keep fighting. They warn that "caving" on Trump's repeated wall promises could hurt his 2020 re-election chances, and other Republicans' as well.
The GOP-led House voted largely along party lines, 217-185, to attach the border wall money to the Senate's bill. House Republicans also tacked on nearly $8 billion in disaster aid for coastal hurricanes and California wildfires.
Some Republicans senators cheered on the House, but prospects in the Senate are grim amid strong opposition from Democrats. Even though Republicans have a slim majority, 60 votes are needed to approve the bill there.
One possibility Friday is that the Senate strips the border wall out of the bill but keeps the disaster funds and sends it back to the House. House lawmakers said they were being told to stay in town for more possible votes.
