Senate Armed Services Committee Chairman John McCain has kicked protesters out of a budget hearing, calling them "low-life scum."

The upheaval came Thursday on Capitol Hill after members of an anti-war group calling itself Code Pink approached a witness table where former secretaries of state Henry Kissinger, Madeleine Albright and George P. Shultz were testifying. The protesters carried signs calling the 91-year-old Kissinger a war criminal.

McCain blurted out, "Get out of here, you low-life scum."

Capitol Police removed the protesters from the room.

The hearing was the third in a series in which the Arizona Republican has called luminaries from the foreign policy world to share their experiences with lawmakers on the panel.
