Characterized by heightened political repression and persecution of left-wing individuals, and a campaign spreading fear of alleged communist and socialist influence on American institutions and of espionage by Soviet agents. After the mid-1950s, McCarthyism began to decline, mainly due to Joseph McCarthy's gradual loss of public popularity and credibility after several of his accusations were found to be false, and sustained opposition from the U.S. Supreme Court led by Chief Justice Earl Warren on human rights grounds. The Warren Court made a series of rulings on civil and political rights that overturned several key laws and legislative directives, and helped bring an end to the Second Red Scare
So when Bush said:
