D.C. Mayor Vincent Gray has moved in recent months to fill hundreds of seats on the city’s boards and commissions, reducing a huge backlog by more than one-third even though more than 400 vacancies remain.

An analysis of public records by The Washington Examiner shows there were 468 vacancies on the District’s 175 panels through mid-June. That’s down from 729 available slots in March, a 36 percent reduction.
