VENICE Louisiana (Reuters) - President Barack Obama will meet with the leaders of a panel he created to probe the worst oil spill in U.S. history on Tuesday, as a giant slick from BP's blown-out Gulf of Mexico well poses a new threat to the coasts of Mississippi and Alabama.
The spill, which has eclipsed the 1989 Exxon Valdez disaster as the biggest in U.S. history, entered its 43rd day as BP Plc prepared a new and untested plan to use a dome to funnel oil gushing from a well a mile beneath the sea to a tanker on the surface.
