Re: MKULTRA/PROJECT MONARCH
The Pike, Church and Rockefeller Commissions were all set-up in 1975 with George Bush, Sr. as DCI.
I would assume the two and one-half tulmultuous years of Colby's tenure they refer to was the time leading up to these investigative committees on intelligence malfeaseance within the CIA.
The director prior to Colby, had passed to him the 693 plus pages of the FAMILY JEWELS.
Apparently, COLBY didn't seem to have a problem reporting to Congress. He felt this would demonstrate the CIA's adherence to the Constitution, but the agency didn't like that he was distancing himself from the White House.
