With Congress already out of town, the government will head toward a shutdown if Trump does not sign the bill Friday.
He added that passing the bill was a "matter of national security" and his "highest duty is to keep America safe".
On Thursday, Paul invested hrs slamming the expense as well as the procedure whereby the regulation is revealed as well as passed, and also showed up to live-tweeting as he checked the procedure.
Kirstjen Nielsen, secretary of the Department of Homeland Security, called the $1.6 billion allocation for the border in the spending bill a "down payment" Friday.
He'd tweeted earlier in the day, "I am considering a VETO of the Omnibus Spending Bill based on the fact that the 800,000 plus DACA recipients have been totally abandoned by the Democrats (not even mentioned in Bill) and the BORDER WALL, which is desperately needed for our National Defense, is not fully funded".
Trump said he signed the measure that had passed the Senate just hours earlier "as a matter of national security", because it dramatically expands military funding and provides for "the largest pay increase" for U.S. troops in over a decade. Telegraphing the outcome, an internal White House television feed advertised the event this way: "President Trump Participates in a Bill Signing". A veto would have resulted in a government shutdown at midnight.
There were conferences with team as well as the legislator in the clothes closet, simply off the Us senate flooring.
Democratic congressman Mark Pocan accused the president of a "loser's bluff". Quote, "I am considering a veto of the Omnibus Spending Bill". "We dare you", Mr Pocan said on Twitter. "I can't sit here and tell you and your viewers that we love everything in the bill", he said on Fox.
The president suggested in a Friday morning tweet that he might reject the 2,000-page package.More news: Tennessee, former AD John Currie agree to $2.5 million settlement
He says, "this is a short term funding, but it's immediate".
Also urging Trump to veto the bill was Sen. "The spending levels without any offsets are grotesque, throwing all of our children under the bus".
"Shame, shame. A pox on both Houses - and parties", the Kentucky senator tweeted after the bill cleared the Senate. But there is no indication that Trump shares those concerns.
Instead, Trump won $1.6 billion to begin building and replacing segments of the wall along the border with Mexico.
In January, the administration proposed $25 billion over 10 years for the wall in a package that would have included a path to citizenship for 1.8 million young immigrants and sharp cuts to legal immigration.
Senate leaders are talking to Risch, hoping to resolve the issue and free the spending bill.
In addition to Paul, Senate leaders had to fight another personnel fire behind the scenes, with Idaho Republican Jim Risch fuming over language that would rename the White Clouds Wilderness in his state for ex-governor Cecil Andrus, a Democrat. It includes about $4 billion to combat opioid addiction and provides more than $21 billion for infrastructure improvements. DeVos simply hasn't learned her lesson, said one senator. "What, does he just want to create more confusion and chaos?" Trump ended the program in September but gave Congress a March 5 deadline to pass a law codifying protections for DACA recipients.
"We have to get a lot of great legislation approved and without the filibuster rule, it will happen just like magic", the president said. Johnny Isakson, R-Ga., of Trump's threat.
"There are a lot of things I'm unhappy about in this bill". Chris Van Hollen, D-Md. Then, there's what he says an hour later. "Time will run out and they will eventually win but if they'd like to do it in a more expeditious fashion, all they've got to do it call me".
Although Trump aides declared Thursday that Trump meant to sign the bill, there were signs of his displeasure with various aspects of it. House Speaker Paul Ryan says no bill that big is ideal.
He noted the deal includes at least some money for new construction along the border.
The conservative wing of Trump's party had panned the bill because of its spending increases and some deficit hawks cheered Trump's Friday morning threat to veto it.
