That didn't take long.

Here's the GOP representative from Arlington Texas, Joe Barton (link):

"BP should bear the full financial responsibility for the accident on their lease in the Gulf of Mexico," Barton said in a written statement. "BP should fully compensate those families and businesses that have been hurt by this accident. BP and the federal government need to stop the leak, clean up the damage, and take whatever steps necessary to prevent a similar accident in the future." 

He added: “I regret the impact that my statement this morning implied that BP should not pay for the consequences of their decisions and actions in this incident."

Apologizing to BP was such a ridiculous stunt.  I'm not surprised to see Barton backing away from his statement.  As as aside, its pretty clear why he made the statement.  Here's 538 on his campaign contributors (link).

UPDATE:  The walk back is only a walk back from the words, not the intent of the statement.  Here's from Sullivan's blog (link).
