 During his tenure in OLC, he authored a number of significant classified opinions providing legal authorization for so-called "enhanced interrogation techniques", which are frequently described as torture.Bradbury was nominated to be the Assistant Attorney General for OLC but individual Democratic Senators put holds on his nomination, preventing the full Senate from voting on it, and Democratic leaders in the Senate instituted "pro forma" sessions of the Senate during scheduled recesses to prevent the President from giving him a recess appointment.Bradbury continued to serve as the acting chief of OLC until the end of the Bush Administration on January 20, 2009.
