Executive Power and the Southern Border Wall

The recent battle in Washington over security at the southern border has raised questions about executive power. President Donald Trump declared a national emergency on February 15 in order to get his border wall built.

Is there a showdown in the Supreme Court between Congress and the President looming over this? Carolee McGrath sat down with Jerold Duquette, Associate Professor of Political Science at Central Connecticut State University for history, context and insight.
