He constantly accused the federal government of being involved with the Communists. This is what initiated the army-McCarthy hearings in the first place. But in the end, his accusations and remarks were decreed as groundless. McCarthy blamed the army and the army blamed him and said that he was stating those remarks to please his senior David Schine and his friend, Roy Cohn (Caute).
Many people in the government were intimidated by Senator McCarthy because of his popularity and his gift of gab. Despite his blames and accusations, people listened to him because he was an excellent orator. But it is unfortunate that he used his skills for the wrong purposes. This is why his sudden decline was his own fault, as was later proved by Edward Murrow. Another reason for McCarthy’s growing popularity was his relation with the Kennedy family. He was in their good books and while the Kennedy family was at its prime, McCarthy took unfair advantage of it. Moreover, the Kennedy’s were Catholics and so was McCarthy and this forged a stronger bond between the Kennedys and McCarthy. This is also why McCarthy gained infinite support when it came to targeting the Communist tribes. Many journalists and critics also claim that for McCarthy, being Communist was more of a personal issue and it was his fault that he amalgamated it with his profession(Caute).
After these remarks began to surface, the Senate took the matter in its own hands. The Senate set up a committee to find the root of the problem. Normally, McCarthy was the one who governed these meetings but as this time he himself was being charged, Karl Mundt was elected as the leader of the committee. He was also a renowned Republican senator. At first the Senate was a little hesitant to make Mundt the head of committee because McCarthy was a lot stronger opponent and he made a rude opponent, but many members of the committee voted in favor of Mundt.
