From The Los Angeles Times:
Former Vice President Dick Cheney personally oversaw at least four briefings with senior members of Congress about controversial interrogation programs, part of a secretive and forceful defense he mounted throughout 2005 in an effort to maintain support for the harsh techniques used against detainees.
The Cheney-led briefings came at some of the most crucial moments for the program, as congressional oversight committees were threatening to investigate or even terminate the techniques used in interrogations, according to lawmakers, congressional officials and current and former intelligence officials.
