The following is a link to the actual government report from the Senate’s Church Committee that formally looked into how the CIA was breaking its own rules to meddle in US domestic affairs in 1975.
Below is a link to the text file that’s even easier for searching.
Page 195 is where the report talks about journalists, ending up with 50 the CIA admitted to having on the payroll or otherwise co-opted. (In Carl Bernstein’s Rolling Stone feature on the same question, he comes up with 400 journalists.) This is also where they review the use of clergy for CIA purposes.
Page 385 starts the section on CIA Drug Testing; not the MK Ultra, but LSD on unwitting subjects, et al.
Page 557 is where they get into the Russians playing the same dirty games.
