December 29, 2011 Justice Department prosecutors are considering the first such charges related to the worst offshore oil spill in U.S. history — a disaster that also killed 11 workers when an oil rig blew up.
December 6, 2011 Halliburton, meanwhile, denies that allegation and accuses BP of fraud and defamation. The two companies are trading charges and blame for the nation's worst offshore oil spill — the April 2010 disaster in the Gulf of Mexico.
October 17, 2011 Anadarko was a minority partner in the project to drill for oil at the Deepwater Horizon site. Eleven workers were killed when the rig exploded in April 2010, and the spill was one of the worst in U.S. history.
September 14, 2011 The worst offshore oil spill in U.S. history started with an explosion and fire that killed 11 oil rig workers in April 2010. BP, investigators say, "was ultimately responsible for conducting operations" at the site.
June 22, 2011 Transocean, the rig owner, BP made all the key decisions that led to the disaster. The British company has pointed the finger at many players. Who is ultimately judged to be responsible will be debated in court.
April 14, 2011 ProPublica and The Washington Post report that many people appear to have cashed in as BP spent billions in the year since the disaster in the Gulf of Mexico. But "others hurt by the spill ended up getting comparatively little."
December 2, 2010 The President’s oil spill commission is likely to recommend that the United States create a new, independent agency to oversee worker safety on offshore drilling rigs and production platforms.
