Washington — A defiant President Donald Trump said Friday he was prepared to keep the US government shut down for as long as it takes — months or even years — to force Congress to provide billions of dollars for a border wall with Mexico.

“This is national security we’re talking about. We’re not playing games,” Trump said following another round of talks at the White House with Democratic leaders on ending the two-week impasse which has shut about 25 percent of the government.

“The southern border is a dangerous, horrible disaster,” he said, decrying illegal immigration, drug smuggling and human trafficking.

“We have to get a structure built,” Trump said, calling on Congress to approve his $5.6 billion request for a “major powerful barrier” made of concrete or steel.

Trump also claimed that some previous US presidents had told him they should have built a wall. None of Trump’s predecessors has ever publicly advocated such a thing.

Describing the situation as a “national emergency,” Trump said he was looking into ways to get a wall built without congressional approval. “I may do it,” he said. “I am allowed to do that.”

Chuck Schumer, the Senate minority leader, said Democrats had urged Trump during what he called a “sometimes contentious” meeting to reopen the federal government, which has been partially shut down since December 22 leaving 800,000 employees furloughed or working without pay.

A handful of those employees held a roadside protest in Maryland on Friday, saying they want to get back to work, WTOP radio reported.

“We told the President we needed the government open,” Schumer said. “He resisted. In fact, he said he’d keep the government closed for a very long period of time. Months or even years.”

Asked by reporters whether this was true, Trump said it was although he added that he hoped the shutdown “doesn’t go on even beyond a few more days.”

“I will do whatever we have to do,” Trump said. “If we have to stay out for a very long period of time we will do that.”

We really cannot resolve this until we open up government.

“We are committed to keeping our borders safe,” Nancy Pelosi, who took over as speaker of the House on Thursday, told reporters following the meeting with the president.

But, Pelosi added, “we recognize on the Democratic side that we really cannot resolve this until we open up government.”

“And we made that very clear to the President,” she said. “Services are being withheld from the American people. Paychecks are being withheld.”
