Donald Vidrine, BP's "company man," overruled the rig's chief mechanic and driller, pushing to speed up the process by removing the drilling mud faster to save BP money on the day of the tragic explosion, according to testimony from oil rig owner Transocean's Doug Brown on Wednesday. "Well, this is how it's gonna be," Vidrine allegedly said when confronted by the other workers from the BP oil spill, according to Brown's testimony, reports the Houston Chronicle. BP's Donald Vidrine did not testify on the BP oil leak as scheduled on Wednesday, citing an unspecified medical condition. The other top BP official on the oil rig, Robert Kaluza, also declined to testify, invoking his 5th Amendment right not to incriminate himself in the oil spill. And a third witness, James Mansfield, Transocean's assistant marine engineer on the Deepwater Horizon, also called in sick, the Coast Guard said. The BP Gulf oil spill may be the worst in US history.
