Republican appointee Matthew Petersen, who was nominated to be a federal judge by President Trump before withdrawing after being unable to answer basic legal questions, announced his resignation Monday.
The move comes days after Petersen and the lone other Republican on the panel blocked the FEC from investigating a complaint alleging that Russian operatives may have illegally funneled money to the Trump campaign through the NRA.
With Petersen out, the six-member panel is down to just three members, one short of the four members they need to take any official action.
“Without a quorum, certain Commission activities will not take place. For example, the Commission will not be able to hold meetings, initiate audits, vote on enforcement matters, issue advisory opinions, or engage in rulemakings,” Republican commissioner Caroline Hunter said in a statement Monday.
