This burst of candor from Ford reminds me of the story from January 1975 when he held a White House luncheon for the editors of the New York Times. Someone asked why Ford had picked such a conservative and defense minded panel to make up the Rockefeller Commission. The president said he needed people who would not stray from the straight and narrow. If they did, they could stumble upon matters that might hurt the national interest. The editor asked "Like what?" Ford replied with, "Like assassinations!" (Schorr, p. 144) Ford added that this was off the record. But reporter Daniel Schorr deduced that since the Rockefeller Commission was investigating domestic matters, Ford must have meant American assassinations.
It still seems like a risky thing to tell a foreign leader, who could have blabbed it to the press back in the day.
