The term "government agency" or "administrative agency" usually applies to one of the independent agencies of the United States government, which exercise some degree of independence from the President's control. Although the heads of independent agencies are often appointed by the government, they can usually be removed only for cause. The heads of independent agencies work together in groups, such as a commission, board or council. Independent agencies often function as miniature versions of the tripartite federal government with the authority to legislate (through the issuing, or "promulgation" of regulations), to adjudicate disputes, and to enforce agency regulations (through enforcement personnel). Examples of independent agencies include the Federal Communications Commission (FCC), Federal Reserve Board, U.S. Securities and Exchange Commission (SEC), the National Labor Relations Board (NLRB) and the Federal Trade Commission (FTC).
