The president appoints and the Senate confirms the FCC’s five commissioners. They serve 5-year terms, unless appointed to fill an unexpired term. One of the five commissioners is designated by the president to serve as chairperson. The chairperson delegates management and administrative responsibility to the managing director of the FCC. To preserve a certain degree of political equilibrium, one political party may only have three commissioners at any one time. No commissioner may have a financial interest in any business related to the work of the commission. The five FCC commissioners supervise all of their organization’s official activities and delegate agency responsibilities to staff units and bureaus.
