Step-by-step explanation:
President Nixon and President Reagan achieved success in molding the federal judiciary to their own political beliefs. President Nixon appointed four Supreme Court justices who aligned with his conservative values, including Chief Justice Warren Burger. Nixon also appointed many conservative judges to federal district and appellate courts.
