Two BP supervisors pleaded not guilty Wednesday to manslaughter charges for failing to prevent a deadly blast that killed 11 workers and unleashed a massive oil spill in the Gulf of Mexico.
Robert Kaluza, 62, and Donald Vidrine, 65, entered the plea in a federal court in New Orleans, where they were appearing with a BP executive charged with obstruction of justice in connection with the 2010 disaster.
