Nixon critics charged that he overstepped his authority as president when he secretly sent America?

Nixon critics argued that he overstepped his authority by secretly sending American troops into Cambodia during the Vietnam War without congressional approval. This action was seen as a violation of the War Powers Resolution and raised concerns about executive overreach. Critics believed it undermined the checks and balances designed to limit presidential power in military engagements. The controversy contributed to growing discontent with Nixon's administration and fueled the anti-war movement.
