US govt angry that BP missed deadlines -Salazar

HOUSTON May 23 (Reuters) - The U.S. government is frustrated and angry that BP Plc (BP.L) has missed "deadline after deadline" in its efforts to seal a blown-out oil well in the Gulf of Mexico, U.S. Interior Secretary Ken Salazar said on Sunday.

BP has agreed to pay cleanup costs beyond the $75 million liability limit set by current U.S. law, Salazar told reporters after visiting BP's U.S. headquarters in Houston.

"If we find they're not doing what they're supposed to be doing, we'll push them out of the way appropriately," Salazar said.
