Supreme Court Will Likely Shut Down Donald Trump's National Emergency Declaration, Rand Paul Predicts

Republican Senator Rand Paul of Kentucky said Sunday that he believed President Donald Trump's national emergency declaration would be rejected by the Supreme Court.

"Without question, the president's order for more wall money contradicts the will of Congress and will, in all likelihood, be struck down by the Supreme Court," Paul wrote in a Sunday op-ed for Fox News.

The Republican senator said he believed "the president's own picks," Supreme Court Justices Brett Kavanaugh and Neil Gorsuch, "may rebuke" the president on his decision to use emergency powers to obtain funding for his long-promised border wall between the U.S. and Mexico.

Paul said that while he supported Trump and the president's "fight to get funding for the wall from Republicans and Democrats alike," he "cannot support the use of emergency powers to get more funding" and would be voting against Trump's national emergency declaration when it came before the Senate.

"Congress clearly expressed its will not to spend more than $1.3 billion and to restrict how much of that money could go to barriers. Therefore, President Trump's emergency order is clearly in opposition to the will of Congress," said Paul. "Moreover, the broad principle of separation of powers in the Constitution delegates the power of the purse to Congress. This turns that principle on its head.

"I must vote how my principles dictate," Paul said. "My oath is to the Constitution, not to any man or political party."

"I stand with the president often, and I do so with a loud voice. Today, I think he's wrong, not on policy, but in seeking to expand the powers of the presidency beyond their constitutional limits," he asserted, adding, "I look forward to working for a constitutional way to deal with our border security issue."

Paul will not be alone in voting against Trump's national emergency as a Republican senator, and his vote could give the Senate enough to oppose the president's declaration.

On Tuesday, the resolution disapproving of Trump's declaration passed in the House, with 13 Republicans voting with Democrats.

Senate Democrats would need at least four Republicans to vote with them for the resolution to pass there. GOP Senators Susan Collins of Maine, Lisa Murkowski of Alaska and Thom Tillis of North Carolina previously suggested they also planned to vote in favor of the measure.

If the resolution does reach Trump's desk, the U.S. leader has promised to veto it, which would represent his first use of veto powers while in office.

In February, the president said that he would "100 percent" veto the measure.
