BP: Tony Hayward Not Resigning

A spokesperson at BP's headquarters in London says any rumors of CEO Tony Hayward's pending resignation are false.

Hayward is under mounting pressure to step aside, most recently from Sen. Richard Shelby, R-Ala., who said Sunday on CBS' "Face the Nation" that the oil company boss "should go".

Shelby said Sunday the fact that Hayward attended a yacht race over the weekend reflects his "gall" and "arrogance," and illustrates why he should not be in charge of the company.

"I thought that was the height, height of stupidity, and I believe myself that he should go," Shelby told Bob Schieffer. "I don't know how he can represent a company in crisis like BP and ignore what's going on in the Gulf of Mexico."

Hayward is to hand over day-to-day operations involving the oil spill cleanup in the Gulf to Bob Dudley, a BP managing director who has helped manage the company's on-the-ground response since May.

BP has said that change was planned prior to the intense criticism of Hawyard over his comments and actions deemed insensitive to the Gulf residents suffering the spill's effects.
