Muriel Bowser, the mayor of Washington D.C. and the longest-serving Black woman in the role, has announced that she will not seek re-election for a fourth term. This decision marks the end of her decade-long tenure, which has been characterized by both significant achievements and challenges, including federal intervention during the Trump administration. With her departure, a competitive mayoral race is expected to unfold, though Bowser has not indicated whether she will endorse a successor or her future plans.
