The arraignment for BP well site leaders Robert Kaluza and Donald Vidrine are slated for Wednesday. The two were indicted earlier this month on manslaughter charges in the death of 11 rig workers. The federal indictment accuses them of disregarding abnormal high-pressure readings that should have been glaring indications of trouble just before the blowout of the well.
A separate indictment charges former BP executive David Rainey with concealing information from Congress about the amount of oil that was spewing from the well.
Their attorneys have vowed to fight the charges.
