Answer:
Joseph McCarthy
Explanation:
Born and raised on a farm in Wisconsin, McCarthy graduated in law in 1935 and in 1939 was elected the youngest judge in state history. At age 33, McCarthy enrolled as a volunteer in the United States Marine Corps and served during World War II. In 1946 he was elected to the United States Senate and after three years without much prominence, in February 1950 McCarthy suddenly stood out on the national scene by stating in a speech that he had a list of "Communist Party members and members of a spy network "employed within the US State Department. Due to the tensions of the Cold War that fueled fears of widespread communist subversion, McCarthy's statement made him the most visible public figure. He became known for his statements that there were a large number of communists, Soviet spies and sympathizers within the US federal government.
During his ten years in the United States Senate, McCarthy and his team became famous and infamous for aggressive investigations into the US federal government and for campaigning against anyone they suspected of being or sympathizing with the Communists.
