House Speaker Nancy Pelosi (D-Calif.) said on Thursday that she hasn't heard any complaints from her members about President Barack Obama's response to the Gulf oil spill.

Pelosi denied any dissent in Democratic ranks over how the Obama administration has handled an oil spill in the Gulf of Mexico that has been leaking for over a month.

"No, I haven't heard those," Pelosi said of rumors of griping among some Democrats in response to the spill. "I honestly can say I've heard no complaints from my members about the way the president has handled it."

The speaker did express frustration, though, toward the Interior Department's Minerals Management Service, whose director, Liz Birnbaum, resigned this morning.

Pelosi said the agency had a "cozy relationship" with the oil industry during President George W. Bush's administration, and that many Bush appointees "are still burrowed in the agency that is supposed to oversee the industry."

"There has to be a systemic change there," Pelosi said.

Obama himself is expected to face questions on the resignation and other elements of the oil spill during a press conference this afternoon. BP, meanwhile, is optimistic that its "top kill" procedure has stalled the flow of oil into the Gulf.
