They would be better off pinning it on Nixon. It’s true he was VP in 1957, but at least he was actually on the committee in the 40’s and his investigations is credited with busting one of their biggest gets, commie Alger Hiss. Which they still hate Nixon for to this day..
In December 1952, at the behest of his father, Robert F. Kennedy was appointed by Republican Senator Joe McCarthy as assistant counsel of the U.S. Senate Permanent Subcommittee on Investigations. He resigned in July 1953, but “retained a fondness for McCarthy.”
So, let’s see. Nixon was on the House committee that located and stopped a bunch of real communists who had infiltrated the government. And Robert Kennedy was an aide to Senator Joe McCarthy.
