Eleanor Holmes Norton delegate Congress District Columbia.

The District of Columbia’s longtime delegate is closing out her career in Congress. Eleanor Holmes Norton filed paperwork Sunday to terminate her campaign for reelection. The 88-year-old veteran of the Civil Rights Movement is the oldest member of Congress. The 18-term delegate has been an advocate for her city’s interests in Congress since 1991. But her effectiveness as the district’s sole voice in Congress came under scrutiny after President Donald Trump’s intervention in the city last year. Norton’s retirement opens up a likely competitive primary to replace her in the overwhelmingly Democratic city.
