“What is wrong with you people?” Stewart asked. “I guess it’s time for our new segment: ‘Please tell me this is rock bottom."
Stewart continued: “Oh, my God. It’s official. Republicans hate the United Nations more than they like helping people in wheelchairs.”
The treaty says all nations should work to ensure that disabled people enjoy the same rights and freedoms as other citizens.
The treaty was backed by Mr Dole, who was disabled in World War II, Arizona Senator John McCain, who sustained disabling injuries in the Vietnam War, Indiana Senator Richard Lugar, the top Republican on the Foreign Relations Committee, and former Attorney General Dick Thornburgh.
The 61-38 vote on the Convention on the Rights of Persons with Disabilities meant the treaty failed to reach the two-thirds majority needed.
The treaty was signed by 155 nations and ratified by 126, including Britain, France, Germany, China and Russia.
The 1990 Americans with Disabilities Act, which sought to protect equal rights for the disabled, became the basis of the UN treaty.
It was negotiated under former President George W Bush's administration and signed by President Barack Obama in 2009.
About 10% of the world's population - or 650 million people - are disabled, UN estimates suggest.
Let's be real here readers the American Taliban dislikes the UN just as much as they hate their own Government. So who loses here, once again those less fortunate.
