Jesus, even I'm getting bored with pointing this out. Former Senator Tom Daschle (emphasis added):
As Senate majority leader at the time, I helped negotiate that law with the White House counsel's office over two harried days. I can state categorically that the subject of warrantless wiretaps of American citizens never came up. I did not and never would have supported giving authority to the president for such wiretaps. I am also confident that the 98 senators who voted in favor of authorization of force against al Qaeda did not believe that they were also voting for warrantless domestic surveillance.
Mind you, you have to be careful about accusing the Bushies of lying, 'cuz some folks purely get their panties in a bunch when you do that.
