WASHINGTON — The Coast Guard said today BP is exhausting every technical means possible to stop the flow of oil in the Gulf of Mexico.

Speaking to reporters at the White House, Coast Guard Admiral Thad Allen said federal law dictates BP is responsible for the cleanup and the government is responsible for overseeing that effort.

Allen said pushing BP out of the way would raise the question of who would take over.

On Sunday, Interior Secretary Ken Salazar said he is not completely confident BP knows what it's doing.

Millions of gallons of oil have spewed from the well that blew out after a drilling rig exploded April 20 off the Louisiana coast.
