Former Holmes Norton staffer lines up to run for her seat, as DC delegate faces growing calls to step down

A former senior aide to Democratic Washington, D.C., Del. Eleanor Holmes Norton is running to unseat his former boss as pressure grows for her to withdraw from the race.

Trent Holbrook previously served as Norton's senior legislative counsel, and he filed papers to run for her seat on Monday. Washington's seat in Congress is not allowed to vote on legislation, but the representative can introduce legislation.

Holbrook defended his decision to run against his former boss in an interview with The Washington Post.
