Sen. John McCain (R-Ariz.) said Sunday that he remains angry at protesters who disrupted a Senate Armed Services Committee hearing last week by calling for the arrest on war crimes charges of former secretary of state Henry Kissinger, who was attending the hearing.

McCain, who chairs the panel, told the agitators, "Get out of here, you low-life scum," as U.S. Capitol Police were removing them from the room. He made no apologies for that remark during an interview Sunday on CNN's "State of the Union."

“These people were physically threatening Henry Kissinger,” McCain said. “Of course, I was outraged, and I’m still outraged. It’s one thing to stand up and protest. It’s another to physically threaten an individual.”

The chairman described Kissinger as "one of the great statesmen of my lifetime,” adding that he thinks the demonstrators are "terrible people that would do that to a 91-year-old man with a broken shoulder.”
