Ordinance Power is the power of The U.S. President as the chief executive to give to issue directives, rules or regulations that have an effect on law. This power arises from both the Constitution and the Acts of Congress. For example, in 1948 President Truman issued an executive order that abolished segregation by race in the U.S. armed forces. This had a direct impact on law.
The Appointment of Power is the power of The U.S. President to appoint individuals of his/her choosing to subordinate positions. Presidents choose people to hold important positions such as delegates, ambassadors, cabinet members, heads of agencies, attorneys and federal judges. The individuals who are appointed to these positions are often chosen based on the Presidents political agenda and the policies of the party represented in the White House. A very recent example is Pres. Donald Trump appointed Betsy DeVos to be the agency head for The Department of Education.
The Removal Power is the power of the U.S. President to remove any of the individuals appointed to the offices listed above. So, just as he/she can hire subordinates (The Power of Appointment), he/she can fire them (The Removal Power). However, this power is widely debated because the Constitution does not specify any details about how this power can be applied or is limited. An example of The Removal Power is In 1920, President Woodrow Wilson removed Frank Myers as the postmaster at Portland, Oregon. This instance of removal is particularly famous because Myers in turn sued the federal government and sparked Supreme Court Case Myers v. United States.
