President Trump signed en executive order to keep "radical Islamic terrorists" out of the U.S. and halted immigration from Muslim countries that are state sponsors of terror or have known extremism elements. The ban includes those from Iran, Iraq, Somalia, Syria, Yemen, Libya and Sudan.



The order bans refugees from these countries for at least 30 days until there can be better measures to vet refugees, specifically those from Syria, and their religious beliefs.



Trump speaking at ceremony officially swearing in Secretary of Defense James Mattis at the Pentagon:





TRUMP: I'm establishing new vetting measures to keep radical Islamic terrorists out of the United States of America. We don't want them here. We want to ensure that we are not admitting into our country the very threats our soldiers are fighting overseas. We only want to admit those into our country who will support our country and love deeply our people. We will never forget the lessons of 9/11 nor the heroes who lost at the Pentagon. They were the best of us. We will honor them not only with our words, but with our actions, and that's what we're doing today.



I am privileged to be here with you and I promise that our administration will always have your back. We will always be with you. And I just want to thank you very much.
