Reports started trickling in last night that the gusher is now gushing mud rather than oil, which would be an early indication that the Top Kill is working and that the leak has been plugged. This morning, the L.A. Times reported that U.S. Coast Guard Admiral Thad Allen is claiming that the operation was a success. Meanwhile, BP is more cautious, denying that the oil leak has been plugged, but saying that the operation is going "according to plan."
Update: 11:07AM EST, Adm. Allen claims to have been "misunderstood" by reporters and is now on message with BP that the operation is simply going according to plan and still in progress.
We'll be updating here as details are confirmed. We've embedded a live stream of the gusher after the break.
