Anderson Cooper on CNN slammed Republican freshman U.S. Senator Mike Lee  from Utah for his false statements about the UN Convention on the Rights of Persons with Disabilities, the result of which, in cooperation with former U.S. Senator and GOP presidential candidate Rick Santorum, and the radical religious right, derailed the treaty.

Senator Lee, the youngest sitting U.S. Senator, was unable to cite any valid reasons for his derailing the UN disabilities treaty, and could not cite any examples of a UN treaty that had any bearing on U.S. law. For Lee, a constitutional lawyer, to be unable to defend his ludicrous positions, is extremely damaging to his credibility.

Lee, after a heated back and forth, says that UN officials sitting on “their perch in a UN office” could tell Americans how to “live their lives.”
