WaPo has the story here. excerpt:
Ramirez's impending departure from the FTC is likely to leave the agency shorthanded with three vacancies on the five-member panel. With one Republican and one Democrat remaining, the FTC will likely be deadlocked in a partisan tie until the Trump administration can fill the other vacancies, which could take months.
Not only will President-Elect Trump get to name those three commissioners, as well as the chair, but the term of incumbent Commissioner Maureen K. Ohlhausen expires in 2019, meaning he will get to name a fourth during his term.
