Nancy Pelosi ‘has standing to sue Trump’ in federal court — and a 'compelling case’: Harvard Law professor

Constitution expert Laurence Tribe on Saturday explained how Speaker Nancy Pelosi has legal standing to sue President Donald Trump over his declaration of a national emergency to build his border wall.

Prof. Tribe has taught at Harvard Law for fifty years and has argued three dozen cases before the United States Supreme Court.

"Trump's actions clearly violate the Congress’s exclusive power of the purse, which our Founders enshrined in the Constitution," Pelosi tweeted. "The Congress will defend our constitutional authorities in the Congress, in the Courts, and in the public, using every remedy available."

Tribe agreed, while explaining a potential remedy at the Speaker's disposal.

"The House of Representatives has standing to sue Trump in the US district court for DC," Tribe noted.

He cited a 2015 case as precedent.

"Speaker Pelosi shouldn't hesitate to take Trump to court. She'll have a compelling case," he explained.

Here are some of his additional thoughts on the national emergency:
