The United States Senate Committee on Armed Services and United States Senate Committee on Foreign Relations begin their closed door hearings into the relief of Douglas MacArthur by U.S. President Harry Truman.

The Committee on Armed Services, sometimes abbreviated SASC for Senate Armed Services Committee, is a committee of the United States Senate empowered with legislative oversight of the nation's military, including the Department of Defense, military research and development, nuclear energy, benefits for members of the military, the Selective Service System, and other matters related to defense policy. The Armed Services Committee was created as a result of the Legislative Reorganization Act of 1946 following the U.S. victory in World War II. The bill merged the responsibilities of the Committee on Naval Affairs, established in 1816, and the Committee on Military Affairs, also established in 1816.

The United States Senate Committee on Foreign Relations is a standing committee of the U.S. Senate charged with leading foreign-policy legislation and debate in the Senate. It is generally responsible for authorizing and overseeing foreign aid programs; arms sales and training for national allies; and holding confirmation hearings for high-level positions in the Department of State. Its sister committee in the House of Representatives is the Committee on Foreign Affairs.

On 11 April 1951, U.S. President Harry S. Truman relieved General of the Army Douglas MacArthur of his commands after MacArthur made public statements that contradicted the administration's policies. MacArthur was a popular hero of World War II who was then commander of United Nations Command forces fighting in the Korean War, and his relief remains a controversial topic in the field of civil–military relations.
