On Monday, GOP presidential candidate Donald Trump called for a "complete and total shutdown of Muslims entering the United States." Less than 24 hours later, Trump is refusing to back down despite mounting criticism from politicians on both sides of the aisle.
Trump is citing President Franklin D. Roosevelt's classification of thousands of Japanese, Germans, and Italians living in the United States during the war as "enemy aliens." He also added he is not endorsing drastic measures such as Japanese internment camps.
Critics range from Republican House Speaker Paul Ryan to the Democratic Senate Minority Leader, Harry Reid.
