"FILE - In this June 17, 2010 file photo, Rep. Joe Barton, R-Texas,questions BP CEO Tony Hayward during the House Oversight and Investigations subcommittee hearing on the role of BP in the Deepwater Horizon Explosion and oil spill on Capitol Hill in Washington. During the hearing Barton accused the White House of doing a $20 billion ""shakedown"" by pushing BP to create compensation fund for Gulf oil victims. Erin Ryan, a tea party activist in Redding, Calif., said Barton was correct to use the word ""shakedown.""  (AP Photo/Alex Brandon, File) (AP)"
