President Donald Trump has threatened to declare a national emergency to circumvent Congress if he cannot reach a deal with Democrats to fund his promised border wall.
He spent most of the day in Texas near the US-Mexico border to draw further attention to his case after negotiations with politicians stalled.
The partial government shutdown dragged into a 20th day with hundreds of thousands of federal workers off the job or working without pay as the wall fight persisted.
Asked about a national emergency declaration, Mr Trump said as he left the White House: “I’m not prepared to do that yet, but if I have to I will.”
He contends such a declaration would allow him to direct the military to begin wall construction.
Because of the Democrats intransigence on Border Security and the great importance of Safety for our Nation, I am respectfully cancelling my very important trip to Davos, Switzerland for the World Economic Forum. My warmest regards and apologies to the @WEF!— Donald J. Trump (@realDonaldTrump) January 10, 2019
“So we’re either going to have a win, make a compromise, because I think a compromise is a win for everybody, or I will declare a national emergency,” he said.
In perhaps an ominous sign for those seeking a swift end to the showdown, Mr Trump announced he was cancelling his trip to Davos, Switzerland, later this month, citing Democrats’ “intransigence” on border security.
He was to leave on January 21 to attend the World Economic Forum.
It was not clear what a compromise might entail.
Mr Trump says he will not reopen the government without money for the wall.
Democrats say they favour measures to bolster border security but oppose the long, impregnable walling that Mr Trump envisions.
He is asking for 5.7 billion US dollars for wall construction.
Mr Trump’s comments came a day after he walked out of a negotiating meeting with congressional leaders, “I said bye-bye”, he tweeted afterwards as efforts to reopen the government fell into deeper disarray.
House Speaker Nancy Pelosi accused the president of engaging in political games to fire up his base.
“I think the meeting was a set-up so he could walk out,” she said.
Affected federal workers face lost pay cheques on Friday, and more people are touched every day by the rollback of government services.
In McAllen, Texas, Mr Trump visited a border patrol station for a roundtable discussion on immigration and border security and got a briefing.
But he had expressed his own doubts that his appearance and remarks would change any minds as he seeks money for the wall that has been his signature promise since his presidential campaign.
“A wheel works and a wall works,” Mr Trump said, mocking Democratic criticism of his plan.
“Nothing like a wall”
Sitting between border patrol officers, local officials and military representatives, Mr Trump insisted that he was “winning” the shutdown fight.
McAllen is located in the Rio Grande Valley, the busiest part of the border for illegal border crossings.
Several hundred protesters were chanting and waving signs opposing a border wall next to the South Texas airport where Mr Trump was set to arrive.
Across the street, a smaller group of protesters shouted back, chanting, “Build that wall!”
And in Washington, US federal workers denounced Mr Trump at a rally with congressional Democrats, demanding he reopen the government so they can get back to work and receive their pay cheques.
Putting the standoff in personal terms, the president tweeted before leaving for Texas: “The Opposition Party & the Dems know we must have Strong Border Security, but don’t want to give ‘Trump’ another one of many wins!”
The White House meeting in the Situation Room ended after just 14 minutes.
Democrats said they asked Mr Trump to reopen the government but he told them if he did they wouldn’t give him money for the wall.
Republicans said Mr Trump posed a direct question to Ms Pelosi: If he opened the government, would she fund the wall? She said no.
Senate Democratic leader Chuck Schumer said Mr Trump slammed his hand on the table.
But Mr Trump, who handed out sweets at the start of the meeting, disputed that characterisation.
He said he “didn’t smash the table” but “should have”.
One result was certain: The shutdown plunged into uncharted territory with no endgame in sight.
On Saturday, Washington appears certain to set an ignominious record for the longest government shutdown in the nation’s history.
The Democrats see the idea of the long wall as ineffective and even immoral.
There is GREAT unity with the Republicans in the House and Senate, despite the Fake News Media working in overdrive to make the story look otherwise.

Mr Trump sees it as an absolute necessity to stop what he calls a crisis of illegal immigration, drug-smuggling and human trafficking at the border.
Mr Trump says Republicans are “very unified”, but his party’s senators have been publicly uneasy as the standoff ripples across the lives of Americans and interrupts the economy.
He has discussed the possibility of a sweeping immigration compromise with Democrats to protect some immigrants from deportation but provided no clear strategy or timeline for resolving the standoff, according to senators who attended a private lunch with him on Wednesday.
