"I don't think they have a real plan yet," Stupak, D-Mich. and member of the House subcommittee on Oversight, said.
Yesterday's hearings revealed a long list of mistakes that possibly led to the April 20 blowout of a well in the Gulf of Mexico, including: bad cement, loose pipes and a dead battery.
Citing an internal BP memo, Stupak told CBS' "The Early Show" that a "culture of incompetence" exists at the oil company.
"We have a serious problem, here," Stupak said.
The gushing well's blowout preventer - supposedly "fail-safe" - never shut off oil flow as intended in emergencies, reports CBS News correspondent Mark Strassmann.That allowed methane gas to enter, possibly triggering the rig's deadly explosion. BP documents show this blowout preventer had design flaws, leaks in its hydraulic system, and a dead battery in its control pod.
