Final answer:
Congress sets the President's compensation, which is $400,000 with an expense account of $50,000. This salary cannot change during the President's term. Historical events show public sensitivity to changes in pay for elected officials.
Step-by-step explanation:
The amount of the President's compensation is set by Congress. According to Section 1 Clause 7, the President receives a pre-determined salary that cannot be changed during their term in office. The current presidential salary is $400,000 with a $50,000 annual expense account. Historical context shows that in March 1873, Congress voted to include a pay raise for the President and other government officials as part of the government's general appropriations bill, leading to public controversy and the eventual repeal of the raises for Congress. Furthermore, the Twenty Seventh Amendment serves as a safeguard by preventing members of Congress from granting themselves a pay increase without the consent of the electorate, since any such increase can only take effect after the next election.
