In the United States, the salary for the president is determined by Congress and outlined in the U.S. Code. Any changes to the president's salary would require legislative action, typically in the form of a bill passed by both the House of Representatives and the Senate and signed into law by the president. The president cannot unilaterally set their own salary; it is subject to the legislative process and oversight.
