The speaker was briefed on waterboarding and other torture techniques used by the White House. She was part of the select group of congressmen and women told of the program. She did nothing to stop it and now claims she was never told it was going to be used. Porter Goss has a different recollection:

“We were briefed, and we certainly understood what C.I.A. was doing,” Mr. Goss said in an interview. “Not only was there no objection, there was actually concern about whether the agency was doing enough.”

For what it's worth, I believe Goss. Getting to the bottom of how the US became a torturing nation is not about one party or another. It's about getting accountability from all those who made it happen.
