President Barack Obama promised that life would return to normal for people living on the stricken Gulf Coast, and BP said new efforts will more than triple the amount of oil it captures from a ruptured undersea well. But the pledges don't reassure some residents."I think that as long as BP is still in control, there's not a lot he can do other than show support for the residents of these Gulf states," Jennifer Jenkins, 34, of Long Beach, said of Obama.The president visited Mississippi and Alabama Monday as part of a two-day stop.
