Answer: After the Vietnam War tug of war between Congress and Presidents LBJ & Nixon, Congress passed the War Powers Resolution, which gives them the power to invoke the requirements that the president must report to Congress within forty-eight hours and obtain the approval of Congress within sixty days when troops are sent into hostilities.
Explanation: The War Powers Resolution was passed on November 7 of 1973, that is to say while Richard Nixon was the president of the United States. The aim of this law was to check the power of the President in issues related to armed conflict. In that way, the War Powers Resolution prevented the president from taking decisions related to warfare without the approval of the United States Congress.
