Answer: D. Shameless
Explanation:
Senator Joseph McCarthy ruined many lives in the early 1950s when he ruthlessly went after suspected communists in service to the American Federal government, amongst others.
At the height of his influence, he made the foolish move of going against the U.S. army and questioned dozens of army officials who had fought bravely for the country.
Even this would not have been too bad if he had not broadcast it on television. The American public saw the ugly side of McCarthyism and were disgusted by what they saw as a shameless attack on the men and women who had sworn to protect the country with their lives as soldiers.
