How did McCarthy contribute to the Red Scare?

Answer 1

Senator Joseph McCarthy contributed to the Red Scare in the early 1950s by aggressively promoting the idea that communist infiltration was widespread within the U.S. government and other institutions. He conducted high-profile hearings and investigations, claiming to expose communist sympathizers and spies, which fueled public fear and paranoia. McCarthy's tactics included making unsubstantiated allegations, leading to the blacklisting and persecution of many individuals in various sectors, including entertainment and government. His actions ultimately exemplified the excesses of anti-communist sentiment during this period.
