George Mulley, a retired investigator with the Office of the Inspector General at the Nuclear Regulatory Commission, leans across a footstool in his suburban Virginia home and pores over a draft of the last investigation he conducted before he officially retiring in 2009.

A copy of a different and final report — which the OIG cobbled together from his draft last year — lies next to it.

“This is a total whitewash,” Mulley says. “They’ve taken out anything that implicates anyone at the NRC.”
