Lawyers for BP sent a letter Monday to the only person who successfully sued the company over the health impacts of its catastrophic 2010 Gulf oil spill, urging former boat captain John Maas and his attorney to stop violating a confidentiality agreement they signed in 2022. Maas was interviewed by WWL Louisiana in his home on top of a mountain in Sparta, Tenn., and brazenly disclosed that he won a $110,000 settlement from the oil giant after a federal judge in Tennessee denied BP’s efforts to stop Maas’ lawsuit from going to trial.
