Jon Stewart hammered Senate Republicans for voting against a United Nations treaty that seeks to protect the rights of disabled people around the world.

The treaty would have had no effect on existing U.S. law, but a handful of Republican Senators voted against it because of concerns it would hinder U.S. sovereignty and the ability of parents to home school their children. The final vote was 61-38, failing to reach the required two-thirds majority.

“What is wrong with you people?” Stewart said. “I guess it’s time for our new segment: ‘Please tell me this is rock bottom.' How did this happen?"

"It’s official. Republicans hate the United Nations more than they like helping people in wheelchairs," Stewart said.
