The War Power Act was first used in response to the actions of which U.S. President?

The War Power Act was first used in response to the actions of Gerald Ford as President of the United States. This Act also known as the War Powers Resolution of 1973 (50 U.S.C. 1541–1548) is a federal law intended to check the president's power to commit the United States to an armed conflict without the consent of the U.S. Congress. The Resolution was adopted in the form of a United States Congress joint resolution by the he 93rd United States Congress. It became effective in the first week of November 1973. It overrode the veto of President Nixon.

What is considered one of the first major challenges to the War Powers Act came in 1975. President Ford was concerned with the deployed military ground personnel to help with the Mayaguez incident which took place between Kampuchea and the United States from May 12–15, 1975. There were major concerns about Ford acting without properly consulting Congress.

Today, critics and most military experts tend to agree that the War Powers Act has rarely worked as intended. According to one study by the Congressional Research Service, presidents have traditionally avoided citing certain provisions of the resolution whenever they submit reports to Congress. As a result, the 60-day time limits in the law has rarely been triggered, and it has never been used to bring an end to a foreign military operation.Congressmen are dissatisfied with the U.S. Executive Branch of government and the minimal level of consultation they have received.
