Final answer:
President Franklin D. Roosevelt tried to influence future decisions of the US Supreme Court by proposing a 'court-packing scheme' to increase the number of Supreme Court justices.
Step-by-step explanation:
President Franklin D. Roosevelt attempted to influence future decisions of the US Supreme Court after it ruled several New Deal programs unconstitutional. He used a strategy known as the 'court-packing scheme,' in which he proposed a bill to Congress to increase the number of Supreme Court justices from nine to fifteen. This would have allowed him to appoint up to six additional justices who supported his policies.
