ANDERSON COOPER: Senator McCain, the president also said that we have not yet detected specific plotting against our homeland. Americans who hear those words might wonder, if that is really the case, then why do we need to take action against ISIS? To that you say what? JOHN MCCAIN: I say that today, we had a hearing, and there was testimony from the counterterrorism people and the Department of Homeland Security. There is Twitter traffic right now and Facebook traffic, where they are urging attacks on the United States of America. And there is a great concern that our southern border and our northern border is porous and that they will be coming across.
Despite some Twitter chatter, there is no evidence ISIS terrorists are trying to slip into the United States from Mexico, Department of Homeland Security officials told Congress Wednesday. Administration officials said they are more concerned about jihadists entering the U.S. legally on commercial airline flights. Administration higher-ups testifying at a House hearing Wednesday threw cold water on scary border scenarios cited by conservatives such as Sen. Ted Cruz of Texas.
