That is the phone number to Russ Feingold's Washinton D. C. office. Feingold has, in the past, said that he feels that the President should be allowed to choose his own cabinet. He voted to confirm people like Ashcroft last time around. This time, among the nominees are condoleezza rice and Alberto Gonzales, both of who seem to believe that torture is okay, and that the US does not have to follow the Geneva Convention. This is an extremely disturbing view point.
Please, call you senator and urge him (or her if you live somewhere outside of Wisconsin) not to vote yes on these confirmations. Herb Kohl's office can be reached at (202) 224-5653. It isn't hard and only takes a minute, but it can make a big difference. Other senators' phone numbers are easily found on the web by googling for their .gov sites.
