What constitutes a constitutional crisis?

Here & Now's Scott Tong talks with Erwin Chemerinsky, dean of the Berkeley School of Law at the University of California, about what would happen if President Trump defies the courts.

Editor's note: The White House issued a statement to Here & Now after this segment first aired, responding to questions about claims it did not comply with a court order barring the deportation of more than 200 Venezuelan immigrants to El Salvador.

"The Administration did not ‘refuse to comply’ with a court order. The order, which had no lawful basis, was issued after terrorist TdA aliens had already been removed from U.S. territory," White House Press Secretary Karoline Leavitt said in a statement. "The written order and the Administration’s actions do not conflict. Moreover, as the Supreme Court has repeatedly made clear — federal courts generally have no jurisdiction over the President’s conduct of foreign affairs, his authorities under the Alien Enemies Act, and his core Article II powers to remove foreign alien terrorists from U.S. soil and repel a declared invasion. A single judge in a single city cannot direct the movements of an aircraft carrying foreign alien terrorists who were physically expelled from U.S. soil.”
