Who did McCarthy witch hunt for?

Senator Joseph McCarthy is best known for his witch hunts against alleged communists in the early 1950s during the Red Scare in the United States. He targeted various individuals, including government officials, Hollywood figures, and members of the media, accusing them of being communist sympathizers or spies without substantial evidence. His aggressive tactics and unfounded accusations created a climate of fear and paranoia, leading to the blacklisting and ruin of many careers. Ultimately, McCarthy's actions are often seen as a violation of civil liberties and an abuse of power.
