Quick summary:
The CIA did indeed use journalists, up to 40 at one time and in some fashions. When they got busted, they said they quit. But they didn't or it wouldn't have come up again 20 years later.
Only one journalist was named, a reporter from The Star.
Senator Hatfield was pushing legislation to ban this when CIA director George HW Bush spoke to him and assured him they wouldn't do it any more. Hatfield withdrew legislation and later regretted it.
A lot of this came to light when a report about Intelligence came out from the Council on Foreign Relations where they recommended using both journalists and clergy.
Some interviewed by the Congressional committee agreed with the reasoning behind the CFR's report. Most disagreed because it would put reporters, clergy (and Peace Corps workers) in jeopardy overseas.
But testimony revealed that in the past the CIA had indeed used both reporters and clergy. Significant was that Sen. Arlon Spectre said there was no law preventing it, but it was left to a CIA Director's policy discretion.
Billy Graham, rest his soul, was not mentioned in either of these reports referred by Q. Nor was he implicated in any way.
