President Barack Obama, speaking in Louisiana, on Friday said he has ordered BP PLC (BP, BP.PLN) to pay all economic injury claims related to the Gulf oil disaster and reiterated that the outcome of a maneuver to plug the mile-deep well remains uncertain.

Obama, amid growing criticism about his administration's response to the disaster, was in the Gulf meeting with local, state and federal officials to survey efforts to plug the well. He said the government is doing whatever it takes to end the spill and stressed that ultimate responsibility for the catastrophe rests with him.

He said he wants to triple the number of people working in areas where oil has come ashore. He also said while oil is coming ashore in some areas, all but three beaches in the Gulf are clean and urged Americans to visit the other beaches to help boost economic activity.

His trip to the region comes a day after he halted much of the planned or current drilling off U.S. coasts, including 33 exploratory operations in the gulf. He said tougher regulations were needed for the oil industry in the wake of the disaster.

His remarks also come after a federal panel released estimates of the spill's size that would rank it the worst in U.S. history, surpassing the 1989 Exxon Valdez disaster.

Obama Friday said the disaster is unprecedented, which means not every judgment the government makes will be "right the first time out." He said the government has one criteria when making decisions: "What's going to best protect and make whole the people and the ecosystems in the gulf?"

He pledged that the government won't abandon the gulf until the leak is plugged and the area is cleaned up.
