Once again, the story gets worse by the day. BBC:
A Deepwater Horizon rig worker has told the BBC that he identified a leak in the oil rig's safety equipment weeks before the explosion.
Tyrone Benton said the leak was not fixed at the time, but that instead the faulty device was shut down and a second one relied on.
BP said rig owners Transocean were responsible for the operation and maintenance of that piece of equipment.
