WATCH: Attorney General To Trump: National Emergency Is 'Solidly Grounded In Law'

     Attorney General William Barr told President Donald Trump his national emergency at the southern border is "solidly grounded in law." Barr assured Trump his national emergency declaration was constitutional after Trump vetoed a resolution that would block his national emergency

     "What you’ve done from a legal standpoint is solidly grounded in law. And from the standpoint of protecting the American people, it’s imperative," Barr said.

     Barr says the national emergency is "clearly authorized under the law and consistent with past precedent."

     "The National Emergencies Act directly authorizes the President, and gives broad discretionary authority to the President, to identify and respond to emergent circumstances that require a decisive response," Barr said.

     "The humanitarian and security crisis we have on the border right now is exactly the kind of emergency that presidents are permitted to address," he added.
