What event caused popular support for Joseph McCarthy begin to fade?

Popular support for Joseph McCarthy began to fade following the Army-McCarthy hearings in 1954. These televised hearings exposed his aggressive tactics and bullying demeanor, particularly during his questioning of witnesses, including members of the military. The public's growing discomfort with his methods and the perception that he was overstepping his bounds contributed to a decline in his popularity. Ultimately, this led to his censure by the Senate later that year.
