Rep. Joe Barton (R-TX) turned a hearing with BP CEO Tony Hayward on its head Thursday by apologizing to BP for what he called a "$20 billion shakedown." Democrats made political hay. Republicans scrambled to distance themselves. Under threat from GOP leaders of losing his job as top House Energy Republican, Barton returned to the hearing to apologize for apologizing. It later emerged that Barton's "shakedown" talking point had been crafted by the Republican Study Committee, a conservative faction that includes 115 of the 178 GOP House members. Barton got more than $100,000 in campaign contributions from the oil industry during this election cycle -- and his top single corporate contributor is Anadarko, which is a 25% stakeholder in the gushing Macondo well. Hayward, while apologetic himself, dodged the panel's questions.
