His crusade came to an end when he turned his attention in the US Army itself in 1954. The hearings were aired, and the public was shocked when they saw how he was treating the witnesses whom were called. 

In August of 1954, the Watkins Committee (named after Senator Arthur Watkins) was formed to evaluate a resolution to censure McCarthy. After two months of hearings and deliberations, the committee recommended that McCarthy be censured and the Senate successfully voted to censure Senator McCarthy in December of 1954.
