Abby Phillip challenges Scott Jennings: Who gets to decide if the US is at war?

A Trump-appointed judge says the president's use of the Alien Enemies Act "exceeds" his power and that his deportations are "unlawful." CNN senior political commentator Scott Jennings says the judge is wrong and the President can use the act because the US is at war with the people who are crossing into the country illegally. Abby Phillip challenges the idea the President and not Congress can decide when the US is at war. #CNN #News
