Answer:
D. give more wartime powers to the president.
Step-by-step explanation:
During the Vietnam War, the United States found itself involved for many years in situations of intense conflict without a declaration of war. Many members of Congress became concerned with the erosion of congressional authority to decide when the United States should become involved in a war or the use of armed forces that might lead to war. It was prompted by news leaking out that President Nixon conducted secret bombings of Cambodia during the Vietnam War without notifying Congress.
