Jury selection has started in the trial of a former BP rig supervisor who faces a pollution charge in the 2010 Deepwater Horizon disaster in the Gulf of Mexico. Both men had faced charges of manslaughter in the death of 11 workers who were killed when the offshore rig exploded, but federal prosecutors backed off those charges. The government did secure a landmark criminal settlement and record civil penalties against the corporation, which BP said would cost the corporation billions of dollars. A former BP rig supervisor goes on trial Tuesday on a misdemeanor charge connected to pollution from the April 2010 Deepwater Horizon disaster in the Gulf of Mexico.
