BS article! It should be titled "he said she said in a Mexican court". Allegations made are totally unsubstantiated and were published for shock value by unscrupulous Barons employee Levisohn to aid his short play. No employees of Transocean are named / involved in this claim dating back to 2008 where one Petrobas employee offered another Petrobas employee a cut of his commission for his support.
Barons is not a credible source for anything.
