Joe McCarthy was picked as the Godfather of Bobby’s daughter, Kathleen Kennedy Townsend. I know that Bobby sought a job from Joe, but I thought that he didn’t get it. I’ll have to re-read “Blacklisted by History” for the answer, according to the author at least.
Both Kennedy and Roy Cohn worked for McCarthy. They both were young hard charging anti-communists who wanted to be McCarthy’s lead attorney for investigations. Cohn got the job.
Blacklisted is an excellent book, extremely well documented. I’ve read it several times.
Joe Kennedy Sr. was a strong supporter of Senator Joseph McCarthy. The elder Kennedy raised money for McCarthy and also helped him gain support. Joe McCarthy dated Joe Kennedy's daughters and JFK and Bobby's sisters Pat and Eunice. Joe McCarthy was close friends with JFK and a frequent guest of the Kennedy family.
Joseph Sr. got a young and inexperienced Bobby a job on McCarthy's staff even though the Kennedy family were Democrats and McCarthy was a Republican. Roy Cohn hated Bobby Kennedy. Cohn called him “a little rich bitch”.
Bobby soon quit because of his anger towards Cohn but remained loyal to McCarthy.
Later when Bobby was working for the Democrat committee investigating McCarthy he almost beat up Roy Cohn after getting into a shouting match with him.
