President Trump said Tuesday that he could build a 'Human Wall' along the border of U.S. forces should Democrats continue to block his border security request.

'Tremendous numbers of people are coming up through Mexico in the hopes of flooding our Southern Border. We have sent additional military. We will build a Human Wall if necessary. If we had a real Wall, this would be a non-event!' he tweeted on the morning of his State of the Union address.

He appeared to be responding to a story in the New York Times detailing how is options for a wall are shrinking.

While he'd previously suggested he could use his national address tonight to announce a national emergency, the president seemed to be moving away from making the declaration in his address to a Joint Session of Congress.

A national emergency declaration to claim his wall money is not favored by all Republicans, and it is very unpopular with Democrats he says he wants to work with on infrastructure and other projects.

Sarah Sanders, the White House press secretary, told reporters Tuesday morning that the president, who just sent more troops to the border, could authorize a third deployment.

She did not say how many forces he was envisioning while fielding a question on the 'human wall' that he'd just tweeted about.

'The president's going to do what is necessary to protect our border. As you know, we've already got troops on the border, and we'll add more if we need to,' she replied.

Sanders had appeared on CNN and Fox News that morning to promote the president's State of the Union address, which she said would be 'visionary' and 'incredible' and 'lay out his successes.'

She told a Fox audience that Trump is '100 percent committed' to and 'focused on border security' and it would be fixture of the evening's address.

'And the president's going to do whatever it takes,' she added. 'And he's going to fight to make sure he has a border.'

The White House spokeswoman seemed to suggest during a brief question and answer session with reporters after her television hits that Trump would wait to see a proposal from a bipartisan committee of lawmakers before he takes further action.

They must present him with a proposal before funding for a host of federal agencies runs out on Feb. 15.

'The president's been laying out that language for weeks. The president's going to continue to talk about the importance of border security, including the wall. And right now, we'll see what the conference comes back with,' she said.

She insisted after that she was not ruling out a national emergency declaration for this evening, as she was pressed on the statement by DailyMail.com.

'I'm not getting ahead of the president,' she insisted.

South Carolina Republican Sen. Lindsey Graham said Monday that unless Democrats in Congress agree to trade $5.7 billion in border wall money for extensions of two immigration programs, President Trump will declare a national emergency and repurpose Defense Department money to build the barrier on his own.

Graham, a former military lawyer and an ally of Donald Trump, said the president has the legal authority to send soldiers to the U.S.-Mexico border and order them to build barriers to protect themselves.

'What's the difference between barbed wire and a sleet slat?' he asked.

Democrats in Congress, Graham said, have treated Trump differently from his two immediate predecessors for personal reasons.

'In 2007,' he said, '634 miles of fencing was authorized by Congress in a bipartisan fashion. February of last year, 46 Democrats voted for $25 billion for a border wall.'

But with Democrats in charge of the House of Representatives, he complained, 'they're trying to deny this president the ability to secure the border like Obama and Bush. Why? Because they hate him. We can't let them get away with it.'

Sen. Lindsey Graham, a reliable ally of President Donald Trump, said Monday in a Greenville, South Carolina speech that the White House will 'go it alone' and build Trump's border wall without Congress if Democrats don't cut a deal with him

President Trump, pictured Sunday with first lady Melania Trump at his golf course in West Palm beach, Florida, has hinted that he will delcare a national emergency and use existing Pentagon money to build his wall if Democrats don't give him $5.7 billion in new funding for the project

U.S. military servicemen are shown installing razor wire at the U.S.-Mexico border on Sunday. Trump is sending 3.750 more troops to install 150 miles of the stuff, and Graham says they could just as easily be building a wall

The current Washington stalemate over a February 15 deadline to fund the government 'probably ends with the president having to go it alone,' Graham told the Republican-leaning First Monday club during a speech the city of Greenville.

The White House has discussed a trade: money to build Trump's long-promised border wall in exchange for legal status for 700,000 'Dreamers' enrolled in the Deferred Action for Childhood Arrivals program, and another 400,000 in the country under Temporary Protected Status.

DACA recipients are illegal immigrants who were brought into the U.S. as children. People with TPS protection are in the U.S. because of natural disasters or wars in their home countries. Most of them are from Central American nations.

Graham said he would blame Democratic lawmakers if a deal doesn't materialize, the Pentagon builds Trump's wall with repurposed money, and the DACA and TPS programs are left to wither on the vine.

'If these TPS people lose their legal status, look in the mirror because you caused it,' he said, directing his comments to Democrats. 'If the DACA recipients, they can't get work permits, it's because you hated Trump more than you liked them.'

Trump can rely on a 43-year-old law to suspend some limitations on his power to spend money if he declares a national emergency exists. Any federal lawmaker can demand a vote to overturn that decision. But unless two-thirds of each house of Congress sides against Trump, he can veto the result.

Speaker of the House Nancy Pelosi has pledged not to give Trump any taxpayer money for building the wall, his signature campagin promise; Graham says she has voted to fund similar projects in the past

If the president decides to disconnect Congress from construction of his border wall, he will sign a funding measure that reopens the government without the $5.7 billion he hsa asked for.

He could also choose to let government funding lapse instead, shutting down a quarter of the government for the second time in two months and sending Congress back to the drawing board.

'We've got until February 15 to figure this out. I'm begging Democrats, be fair to the president and he will be fair to you, regarding the temporary displacement program, TPS, and DACA,' Graham said Monday.

The colorful senator framed the border wall debate over and over as a study in hypocrisy.

'Every Democrat who's saying "Not a dollar for the wall" voted for billions of dollars for a wall on their watch,' he said, recalling proposals shepherded by the bipartisan 'Gang of Eight' in 2013.

'Forty-six billion dollars for border security! We did everything but put alligators on the border. Eight billion for a barrier! They were bragging about how tough they were.

'A border patrol agent every 1,000 feet! Now they want to abolish ICE.'

'Not one Democrat complained' when President Barack obama deployed military servicemen and women to the southern border, Graham said.

And with 3,750 new troops headed south because of Trump's orders, he claimed, setting up barriers is a matter of protecting themselves as much sa protecting the United States.

The current deployment is set to install 150 miles of razor wire.

'We're not doing anything exotic here. If a president can send a soldier to the border, not to enforce border law but to provide security, why can't that soldier put up a barrier while they're there?' he asked.

'The last three presidents have sent troops to the border. They don't go for free. We pay them to go there. We pay for them while they stay. And they're putting up barbed wire,' Graham added.

'What's the difference between barbed ware and a sleet slat? I'm confident the president has the legal ability to do this. I'm hoping he does not have to go down this road.'
