I wouldn't get on Burgess' case. The quote is brief and without context. I'm suspicious that it was cherry-picked. Instead, I'd wager it was delivered in response to a question like "Does Joe Barton speak for the Republican party"?
And that there is much missing context to his remarks...
Burgess said that any one on the Congressional committee could do Tony Hayward’s job. Does that include Henry Waxman? These get-along gang Republicans need to knock it off and see the big picture. Instead, they all cower to the media and accept the premises set by the Democrat on who are the good guys and who are the bad guys
