The Obama administration has sent another multimillion-dollar bill to BP and other parties being held responsible for the oil spill in the Gulf of Mexico.

The latest bill, the third in the nine weeks since the Deepwater Horizon oil rig collapsed, is for $51.4 million.

The White House said in a statement Monday night that BP and others have already paid the first two bills, totaling nearly $71 million.

The latest bill is based on specific federal expenses, including those associated with the response of more than two dozen federal entities and state agencies.
