Gulf oil spill - How bad is the environmental damage from the ongoing oil spill in the Gulf of Mexico? How will it affect plant and animal life - and for how long? Those are among the questions to be discussed at a congressional hearing scheduled to begin at 10 a.m. ET Friday.
Meanwhile, a BP official says a gusher of oil pouring from its damaged Gulf of Mexico well could be shut off as early as next week. BP Managing Director Bob Dudley said Thursday night the company will pump fluids into the well this weekend in the beginning of a process that - if successful - could lead to the leak finally being closed off in a matter of days. CNN's Ed Lavandera reports there is still some controversy over the cleanup - including BP's effort to use other substances to disperse the oil gushing from their pipes - and the fact that much of the dispersant remains sitting in an industrial park.
