WASHINGTON (AP) - Hours after shuttering much of the federal government, feuding Democrats and Republicans in Congress spent Saturday dodging blame for a paralyzing standoff over immigration and showed few signs of progress on negotiations needed to end it.

The finger-pointing played out in rare weekend proceedings in both the House and Senate, where lawmakers were eager to show voters they were actively working for a solution - or at least actively making their case why the other party was at fault. The scene highlighted the high political stakes for both parties in an election-year shutdown whose consequences were far from clear.

"The American people cannot begin to understand why the Senate Democratic leader thinks the entire government should be shut down until he gets his way on illegal immigration," said Senate Majority Leader Mitch McConnell, R-Ky., hours after a last-chance Senate vote failed.

Democrats refused to provide the votes needed to reopen the government until they strike a deal with President Donald Trump protecting young immigrants from deportation, providing disaster relief and boosting spending for opioid treatment and other domestic programs.

Democrats feel "very, very strongly about the issues" said Sen. Chuck Schumer of New York, the Democratic leader, adding that he believes "the American people are on our side."

The fighting followed a late-night vote in which Senate Democrats blocked a House-passed measure that would have kept agencies functioning for four weeks.

Republicans began the day hopeful they might pick off Democratic support for a three-week version and bring the episode to a quick end. Democrats are insisting on an alternative lasting only several days - which they think would pressure Republicans to cut an immigration deal - and say they'll kill the three-week version when the Senate votes on it by early Monday.

The shutdown came on the anniversary of Trump's inauguration. As lawmakers bickered in the Capitol, protesters marched outside in a reprise of the women's march from a year ago. The president remained out of sight and canceled plans to travel to his resort in Florida for the weekend. He did tweet, making light of the timing by saying Democrats "wanted to give me a nice present" to mark the start of his second year in office.

Trump worked the phones, staying in touch with McConnell, while White House legislative affairs director Marc Short and budget chief Mick Mulvaney met at the Capitol with House Republicans. GOP lawmakers voiced support for the White House stance of not negotiating while the government was shuttered.

Tempers were short and theatrics high. Lawmakers bickered over blame, hypocrisy and even the posters brought to the House floor. While neither chamber voted on a measure to open the government, the House did vote on whether a poster displayed by Republican Rep. Bradley Byrne of Alabama violated the House rules on decorum. The House voted to allow the poster, which bore a photo of Schumer and the quote "the politics of idiocy."

While Republicans blamed the breakdown on Schumer, Democrats increasingly focused their messaging on criticizing Trump, whose popularity is dismal. Democrats were using his zigzagging stance in immigration talks - first encouraging deals, then rejecting them - to underscore his first, chaotic year in office.

"Negotiating with President Trump is like negotiating with Jell-O," Schumer said.

Short compared Democrats' actions to "a 2-year-old temper tantrum."

Republicans seemed content to hope additional Democrats will break as pressure builds and the impact of the shutdown becomes clearer.

In the late-night vote blocking the bill preventing a shutdown, five Democrats from states Trump won in the 2016 election voted to keep government functioning. In a sign that moderates are feeling pressure, more than a dozen centrist senators from both parties have been trying to craft an immigration and spending compromise that party leaders would embrace, but they've fallen short so far.

Republicans argued that Democrats were blocking extra Pentagon funds by keeping government closed and thwarting a long-term budget deal.

"I question if Senate Democrats are really united," Short told reporters. "We think there'll be more today and hopefully they'll continue to see that it's not wise to hold our troops hostage."

But pressure on Republicans could mount with the new workweek Monday and the impact of the federal shutdown becomes more apparent to people.

While the Statue of Liberty - the nation's emblem of its immigrant past - and Philadelphia's Liberty Bell were closed Saturday, visitors had access to other iconic national parks like Yellowstone. Interior Secretary Ryan Zinke tweeted a photo of himself talking to students at the World War II Memorial in Washington, blocks from White House.

Social Security and most other safety-net programs were unaffected by the lapse in federal spending authority. Critical government functions continued, with uniformed service members, health inspectors and law enforcement officers set to work without pay. But if no deal is reached before Monday, hundreds of thousands of federal employees will be furloughed.

For leverage, Democrats were banking on Trump's wobbly presidency and the GOP's control of the White House, the House and Senate - a triumvirate that until now had never allowed a government closure to occur.

"Republicans in Congress plunged head-first into the Trump shutdown," Schumer told reporters. House Minority Leader Nancy Pelosi, D-Calif., called Republicans "so incompetent and negligent that they couldn't get it together to keep the government open."

Which party's strategy would succeed remained open to debate.

Retired Sen. Judd Gregg, R-N.H., a veteran of shutdown wars, said he believed Democrats believe "the more chaos they can create the better." He said Schumer's tough strategy was "a gross overplaying of his hand" and predicted Democrats would eventually relent.

Former Rep. Nick Rahall, D-W.Va., said both parties needed to be cautious.

"It's obvious that Democrats are playing to their base and Republicans are playing to their base," he said. "Everybody loses. It just feeds into the fed-up atmosphere of the American people."

Democrats have been seeking a deal to protect so-called Dreamers. Around 700,000 of them have been shielded against deportation by the Deferred Action for Childhood Arrivals program, or DACA, which Trump halted last year. He's given lawmakers until early March to pass legislation restoring the protections, but he's demanded added money for his proposed border wall with Mexico as a price.
