A day earlier, he said he was not ready to do it "right now".
Trump spoke after lawmakers had adjourned for the weekend, precluding any possible action until next week.
"I do think if we reopen the government, if the president ends this shutdown crisis, we have folks who can negotiate a responsible, modern investment in technology that will actually make us safer", Democratic Senator Chris Coons of DE said on Fox. But to understand that plan you would have to understand the fact that I won the election, and I promised safety and security for the American people.
Trump has tried on a number of occasions to blame Democrats for the government shutdown, such as when he tweeted in December that "Senator Mitch McConnell should fight for the Wall and Border Security as hard as he fought for anything".
Trump threatened anew that the shutdown could continue indefinitely. He said he was giving Congress a chance to "act responsibly".
Graham echoed Trump by blaming the three-week long government shutdown on Democrats - specifically House Speaker Nancy Pelosi who joked she would give Trump $1 for the border wall. Paychecks were due Friday, but many workers received stubs with zeroes.
About 800,000 federal workers missed their pay for the first time Friday - at least some receiving pay stubs for $0.00 - as unions sued the government for requiring their members to work without pay.More news: Trump warns Turkey of economic devastation if it hits Kurds

"I think it ends when the Senate Republicans say we've had enough". On Friday, though, he said he wasn't rushing to use that option - which would be challenged in court and, if not overturned, establish a precedent expanding the power of future presidents who could include Democrats.
The public generally is more apt to blame the President, with 55% saying he is more responsible for the shutdown than are Democrats in Congress, while 32% say the blame rests mostly with the Democrats.
Nevertheless the administration has accelerated planning for it.
He denied this allegation and insisted that the White House couldn't be in chaos due to the fact that "there's nearly nobody in the W.H. but me, and I do have a plan on the Shutdown".
But Trump has turned his single-minded push for more walls into a political crusade that opponents say is a stunt to stoke xenophobia in his right-wing voter base while willfully ignoring the border's complex realities.
Concerning the allocation of blame, 53 per cent say Trump and the Republicans are mainly at fault, and 29 per cent blame the Democrats in Congress.
White House press secretary Sarah Sanders did not immediately respond to PEOPLE's request to clarify who is now in the White House with the president.
The investigation became a part of special counsel Robert Mueller's inquiry into potential collusion between Russian Federation and the Trump election campaign. "This is a big diversion, and he's a master of diversion", she told reporters. "The easiest solution to the shutdown, just give President Trump the money", he said. "We believe the government should be opened".
"Congress has to do its duty, and the Democrats have to help us", Trump said. Marco Rubio (R-Fla.) said this week. "But those same conservatives, I'm sure if it's deployed, would embrace him as having done all he could do to negotiate with Democrats".
