Sen. John McCain took on Sen. Rand Paul tonight on “Hannity”over his refusal to support Syrian rebels.

“Has Rand Paul ever been to Syria? Has he ever met with ISIS? Has he ever met with any of these people?” he asked.

“I’m not trying to start a fight, Senator,” Hannity said.

​Sen. McCain on ISIS: ‘Kill Them’

“No, no, no, were going to have a fight because it’s patently false. This is the same Rand Paul that said we didn’t want to have anything to do with… anything to do in the Middle East, by the way. I don’t want to get in a fight with him at all, but it’s not true. I know these people, I’m in contact with them all the time. And he is not, he is not.”

McCain also told “Hannity” that the Free Syrian Army is being attacked by both Bashar Assad and ISIS, suffering hundreds of casualties.
