Trump directs Army Corps of Engineers to find money to help fund border wall: Sources

The White House has directed the Army Corps of Engineers to find money is its own budget that could be used to fund the president’s desired border wall under a national emergency declaration, multiple sources familiar with the matter told ABC News.

The White House has specifically asked the Army Corps of Engineers to examine what funds could be redirected to the border wall from a $13.9 billion February 2018 emergency supplemental that was designed to fund more than 50 disaster relief projects, including in California, Florida, Texas, and Puerto Rico, among other states, according to a congressional aide with knowledge of the matter.

One U.S. official said the money could be used to build as much as 315 miles of border wall under the direction of the Army Corps of Engineers.

The White House did not immediately respond to request for comment.

President Donald Trump toured a portion of the southern border and visited with border patrol agents and local leaders in Texas on Thursday as he continued to make his case for a wall along the southern border to stop illegal immigration.

His trip came on the Day 20 of a partial government shutdown triggered by the president's demand that Congress pay $5.7 billion for a border wall, which Democrats refuse to do.

During a roundtable discussion at the border patrol station in McAllen, the president again contended – falsely – that he never said Mexico was going to provide a direct payment for a border wall and attempted to gloss over his past comments to the contrary by arguing he simply intended for the wall to be paid for through the revised NAFTA agreement.

“When I say Mexico is going to pay for the wall, that’s what I said, I didn’t say they are going to write me a check,” Trump said. “I didn’t mean please write me a check, I mean very simply, they are paying for it in the trade deal.”

The president again blasted Democrats, claiming falsely that “Democrats will not fund border security plain and simple” and said their position of "no barrier, no wall is indefensible.”

Asked how long he thought the shutdown could continue, the president wouldn’t offer a prediction but continued to dangle the possibility that he may declare a national emergency as a way to circumvent Congress.

As he left Thursday morning to head to the border, Trump said he "probably ... I would almost say definitely" declare a national emergency to get funding for a border wall if he can't reach a deal with congressional Democrats. "I would say 100 percent," the president continued. "I don't want to say 100 percent because maybe something else comes up."

While the president continues to say he'd rather make a deal with Congress, he again lashed out at Democrats over the current impasse, denied that he pounded on the Situation Room table and said he didn't "rant or rave" at the latest round of White House talks Wednesday before walking out. "I didn't raise my voice. That was a lie," Trump said.

"I don't have temper tantrums," the president said, pushing back on how Senate Minority Leader Chuck Schumer had characterized how Trump had acted when House Speaker Nancy Pelosi had again told him "no" when he asked whether Democrats would agree to wall funding if he re-opened the government.

Pelosi challenged Trump’s desire to not only build a border wall but to end the partial government shutdown.

“I don’t even know if the president wants the wall,” Pelosi, D-Calif., doubted during a news conference at the Capitol. “I think he just wants just wants the debate on the wall.”

Pelosi recapped her version of the “soap opera” atmosphere of negotiations with the White House, dubbing Trump as “unpresidential” in a meeting with congressional leaders on Wednesday afternoon when he walked out in protest of Democratic objections to building a border wall.

Pelosi suggested Trump lied when he recounted his version of that exit to reporters, claiming that Democratic objections to “border security” more broadly prompted his premature departure.

“He knows, the people in the room know, that that is not what happened,” Pelosi said. “What he said, ‘In 30 days will you support a wall?’ And I said 'no.' He went out and said something completely different because he knows we all support border security and that there’s a better way to do it.”

The president also said China was more "honorable" in negotiations than the Democrats.

"We're negotiating and having tremendous success with China, and I find China, frankly, in many ways, to be far more honorable than Cryin' Chuck and Nancy. China is actually much easier to deal with than the opposition party," Trump said.

Pelosi cracked the door open to cutting a deal through comprehensive immigration reform, even before the government reopens, but pointed to the president’s obsession with the border wall as an obstacle to negotiations on a broader agreement.

“We haven’t had that discussion. What we’re talking about now is just the president’s insistence on a wall,” Pelosi said. “We need to have comprehensive immigration reform.”

Nevertheless, Pelosi said her aides have continued exploring options at the staff level with the White House, but charged the administration keeps changing its position.

“We have been having conversations. We don’t want to be a backdrop for the president to stomp the table and get up and walk out,” Pelosi said. “Our staff all weekend - Saturday, Sunday, have been engaged in these conversations.”

“The president just keeps upping the ante,” Pelosi continued. “In fact, I said to him you’re moving the goal post so many times, they are out of the stadium.”

Pelosi said Democrats have offered to fund all the border security elements from the administration’s budgetary request for Homeland Security – excluding the wall.

“Don’t think of this as normal, because as I say the goalposts keep getting moved,” she said. “But what we did give the president, the White House, is exactly what the Homeland Security department asked for in the budget. But they’ve moved the goalposts.”

Also on Thursday, the president tweeted that he had canceled his trip to Davos, Switzerland, 11 days ahead, for the World Economic forum, blaming the shutdown -- and Democrats.

The White House has said the president's trip to Texas, part of his PR blitz for a border wall, was designed to allow him to meet with those individuals who are "on the front lines" of what they have called a "national security and humanitarian crisis."

He also made his way to the Rio Grande, the winding river separating the U.S. and Mexico.

Whether the president has the legal authority to build a wall by declaring a national emergency -- in which he would circumvent Congress to get military funding for the project -- was under review by White House lawyers, but Trump said he had the power to do so.

"The lawyers have so advised me," Trump said. "I'm not prepared to do that yet, but if I have to, I will. I have no doubt about it, I will. I have the absolute right to declare," Trump said. Later, he added he has a "tremendous" amount of funds available if he chooses that route.

Pelosi refused to tip her hand regarding how the House may react if Trump declares a national emergency to build the wall without congressional approval, but she expressed doubt that congressional Republicans would be satisfied if the president took executive action to circumvent Congress.

“If and when the president does that, you will find out how we will react. But I’m not going to that place now. But I think the president will have problems on his own side of the aisle for exploiting the situation in a way that enhances his power. But not to go there. Let’s see what he does,” she said. “Right now there’s a path. Open up government. Let’s have this discussion on where we can agree on the best ways to protect our borders, to secure our borders, to do so in a way that honors our values.”

Should the president go forward with the move, it would almost certainly be challenged in court.

“I don’t think he really wants a solution,” Pelosi stressed. “I think he loves the distraction that this is from his other problems and that’s most unfortunate. It’s a luxury our country can’t afford under any circumstance. It’s certainly a luxury we can’t afford when he has shut down government, takes pride in it, and says months or years. That’s not the action of a responsible president of the United States.”

The White House has struggled to make the case that there is, in fact, a crisis at the border, with the number of illegal apprehensions trending downward over the last two decades. But the administration points to an uptick of illegal border crossing apprehensions in recent months as evidence.
