NOW do you know what waterboarding is?

Here's what happens when Senators don't forget what they were working on after the cameras go home (PDF):

Dear Attorney General Mukasey:

During the hearing on your nomination to be Attorney General and in your answers to questions submitted for the record, you repeatedly refused to answer questions related to interrogation techniques on the grounds that you had not yet been briefed on the CIA's interrogation and detention program. I was disappointed with these responses. Familiarity with the CIA program should have been irrelevant to a legal opinion about practices such as waterboarding, which have been employed by dictatorships for generations and historically condemned by our own government.

Nonetheless, now that you have been sworn in as our nation's Attorney General and presumably have been briefed on the program, I urge you to provide your views on its legality to Congress at the earliest possible date.

[...]

Sincerely,

Russell D. Feingold
UNITED STATES SENATOR

Well?
