"I'm ashamed of what happened in the White House yesterday," said Rep. Joe Barton (R-Tex.) during a hearing on Thursday morning with BP's CEO Tony Hayward." I think it is a tragedy in the first proportion that a private corporation can be subjected to what I would characterize as a shakedown -- in this case a $20 billion shakedown -- with the attorney general of the United States, who is legitimately conducting a criminal investigation and has every right to do so to protect the American people, participating in what amounts to a $20 billion slush fund that's unprecedented in our nation's history, which has no legal standing, which I think sets a terrible precedent for our nation's future."
