Lucius Quintus Cincinnatus Lamar, United States v. McDonald — Opinion of the Court
“ The compensation paid to public officers of the United States for their services, or for traveling expenses incidental thereto, is always under the control of congress, except in the cases of the salaries of the president, and the judges of the courts of the United States. As said by this court in Embry v. U.S., 100 U.S. 685: 'All agree that congress has full control of salaries, except those of the president and judges of the courts of the United States. The amount fixed at any one time may be added to or taken from at will. ”
