Myers v. United States, 272 U.S. 52 (1926), was a United States Supreme Court decision ruling that the President has the exclusive power to remove executive branch officials, and does not need the approval of the Senate or any other legislative body.

Humphrey's Executor v. United States, 295 U.S. 602 (1935), was a United States Supreme Court case regarding the powers that a President of the United States has to remove certain executive officials of a "quasi-legislative," "quasi-judicial" administrative body created by Congress, for purely political reasons and without the consent of Congress.

In Myers, the ruling pertained to officials of the EXECUTIVE BRANCH. The President is the head of the Executive Branch and, in effect, all Executive Branch officials come under his direct authority and control.

In Humphreys, the ruling pertained to officials of ADMINISTRATIVE bodies of certain agencies CREATED BY CONGRESS. Congress is the LEGISLATIVE BRANCH of Government. The "officials' referred to in Humphrey are appointed by Congressional action and not by the President.

THUS: The Myers case refers to employees of the Executive Branch of government and the Humphrey case refers to employees of the Legislative Branch of government.
