On December 15, Federal Communications Commission (FCC) Chairman Tom Wheeler announced his resignation. Wheeler will leave office on January 20, 2017, the date of the inauguration of president-elect Donald J. Trump.

Because Commissioner Jessica Rosenworcel was not confirmed by the Senate for a new term and will not be with the FCC after January 3, until new commissioners are appointed, the FCC will have a 2-1 Republican majority on the day Trump is sworn in as president. The five-member FCC may only have three commissioners from a single political party. One of the responsibilities of the FCC is enforcement of broadcast political advertising.
