President Barack Obama is in charge of efforts to shut down, the worst oil spill in U. S. history. Obama admitted that U. S. Government must rely on oil giant BP and that it does not have the technology or expertise.

He was to attend a meeting Friday at the U. S. Coast Guard Station in Grand Isle, La., by Adm. Thad Allen. He would be paying a visit there for the second time since the disaster began with an April 20 explosion at the drilling rig Deepwater Horizon, which took the toll on two.

Obama declared at a White House news conference, “I take responsibility. It is my job to make sure that everything is done to shut this down”.

The oil has been gushing forth at a rate 2 1/2 to five times higher than the estimation of BP and the U. S. Coast Guard, as per the Government scientists.

The well is spewing between 504,000 gallons and more than 1 million gallons, in a day. According to an estimate by the scientists, about 18 million gallons have spilled so far. About 39 million gallons have leaked, in the worst scenario.

This Gulf spill has far surpassed the size of the previous largest U. S. oil spill, which is also called, the 1989 Exxon Valdez disaster, in which a tanker ran ashore in Alaska and spilled nearly 11 million gallons.
