Who was the prominent U.S. senator who conducted Senate hearings designed to remove suspected Communists from the U.S. military and from government jobs?

The prominent U.S. senator who conducted hearings to remove suspected Communists from the military and government jobs was Joseph McCarthy. His efforts in the early 1950s, known as McCarthyism, involved aggressive investigations and accusations against individuals he claimed were associated with communism. This period was marked by heightened political paranoia and led to significant consequences for many, often based on flimsy evidence. McCarthy's tactics ultimately faced backlash and contributed to his decline in influence.
