President Trump was pleased with constitutional law scholar Alan Dershowitz’s defense of him over his firing of former FBI Director James Comey, calling the Harvard Law professor’s analysis on Fox News a “must watch” interview. 

“A must watch: Legal Scholar Alan Dershowitz was just on @foxandfriendstalking of what is going on with respect to the greatest Witch Hunt in U.S. political history. Enjoy!” Trump wrote on Twitter.

Dershowitz, a lifelong Democrat, said Trump has the constitutional right as president to fire his FBI director. 

“You cannot charge a president with obstruction of justice for exercising his constitutional power to fire Comey and his constitutional authority to tell the Justice Department who to investigate, who not to investigate,” Dershowitz said during an interview with Fox News.
