Her name is Bunnatine "Bunny" Greenhouse. She blew the whistle when her employer, the US Army Corps of Engineers, gave a no-bid $7bn contract to the Halliburton subsidiary Kellogg, Brown and Root (KBR) as the US was about to invade Iraq. She was doing her job, trying to ensure a competitive bidding process would save the US government money. For that, she was forced out of her senior position, demoted and harassed. Bunny Greenhouse told her superiors that the process was illegal. She was overridden. She said the decision to grant the contract to KBR came from the office of the secretary of defence, run by VP Cheney's close friend, Donald Rumsfeld.
