On August 31, Federal Election Commission (FEC) Vice Chairman Matthew Petersen will leave the agency, resulting in an FEC without the minimum quorum of four commissioners to make decisions on regulations or enforcements.

The FEC requires at least four commissioners to agree for any official action.

Peterson, who has served on the FEC for 11 years, announced his resignation on August 26 with a letter to the President Trump without stating a reason for his leaving.

A replacement for Petersen, a Republican, must be selected by the president and then confirmed by the U.S. Senate.

No more than three members of the FEC may be registered with the same political party.

The remaining FEC commissioners will be Chair Ellen L. Weintraub, a Democrat, Caroline C. Hunter, a Republican, and Steven T. Walther, an Independent.

On December 17, the Federal Election Commission (FEC) elected Matthew Petersen as its chairman and Steven T. Walther as its vice chairman for 2016.

Peterson has been a commissioner with the FEC since 2008 and Walther has been a commissioner since 2006. Each previously served as both chairman and vice chairman. They are two of the four commissioners serving with expired terms. Normally, each member serves a six-year term with a rotating chairmanship among the members with no member serving as chairman more than once during his or her term.
