That was John Mitchell, Nixon's AG (1972): "Katie Graham's gonna get her tit caught in a big fat wringer if that's published", predicting what would happen to the publisher of the Washington Post, if they published a story about a "Secret GOP Fund" that was used to gather information about Democrats.

I heard that term in 1962...10 years before John Mitchell used it. He might be the first cabinet member to use the term but I doubt that. Wringers on washing machines were history by 1972.
