Senator Carl Levine has called Dick Cheney a liar for claiming classified documents demonstrate torture saved American lives.  The Senator, who is Chairman of the Senate Armed Services Committee, said he has seen the documents Cheney is always referring to, and

“those classified documents say nothing about the numbers of lives
saved, nor do the documents connect acquisition of valuable
intelligence to the use of abusive techniques. I hope that the
documents are declassified, so that people can judge for themselves
what is fact, and what is fiction.”
