A congressional probe has found the US Army paid more than $83 million in bonuses to the military contractor KBR, despite its responsibility for the electrocution deaths of at least four troops in Iraq. On Wednesday, Senate Democratic Policy Committee chair Byron Dorgan accused the military of “stunning incompetence” for rewarding KBR. In addition to the four electrocution deaths, hundreds of troops have received electrical shocks because of KBR’s electrical work in Iraq. The committee’s probe says more than half of the bonuses were awarded after the Pentagon first heeded warnings about the electrocutions. KBR is a former subsidiary of Halliburton, the company formerly run by Dick Cheney.
