Answer

Answer:

D. claiming to have a list of communists in the government.

Brief Explanation:

Joseph McCarthy became well - known for his anti - communist crusade, especially his claim of having a list of communists in the government, which led to the era of McCarthyism. He did not defeat Eisenhower in 1956, nor was his main claim to fame related to the Rosenberg case criticism or refusal to cooperate with HUAC.
