"GRAND ISLE, La. – BP reported some oil was flowing up a pipe Friday from a cap it wrestled onto its broken Gulf of Mexico well but crude still spewed and it was unclear how much could be captured in the latest bid to tame the nation's worst oil spill.

President Barack Obama was set to visit the Louisiana coast Friday, his second trip in a week and the third since the disaster unfolded following an April 20 oil rig explosion.

The government's point man for the crisis, Coast Guard Adm. Thad Allen, said the cap's installation atop a severed pipe late Thursday was a positive development but it was too early to tell if will work. The funnel-like lid is designed to channel oil for pumping to a surface tanker."
