Congress knew.

This exclusive story confirms that House Speaker Nancy Pelosi and other congressional leaders knew about waterboarding, but didn't speak up.

This fact suggests that the leaders (including those on the intelligence committees) knew what the results of interrogations achieved, if anything. Is former Vice President Dick Cheney right when he claims that other memos show they were productive? Pelosi et al, if they're honest, can help clear this up.

But they won't, because it won't serve their partisan needs.

And why won't Pelosi tell her colleagues in the House? (See the video.)
