We should station McCain on the southern border. He knows those IS[IS] guys pretty well - was once pretty good friends with them from what I hear - so he should be able to recognize them and point them out to the Border Patrol.
But the State Department and all the dems said that was just the Republicans trying to scare people. They have NO CLUe who is coming in here. The border needs to be closed and militarized
Indeed he is, and pretty good friends with all the southern border interlopers, if his previous stances on border security and building a border fence can be believed.
