This bill would change federal law to allow the United States flag to be flown at half-staff when the Mayor of the District of Columbia dies. Currently, federal flag code permits half-staff display for deaths of the President, Vice President, members of Congress, governors of states and territories, and certain other high-ranking officials, but the D.C. Mayor is not included in that list. The legislation would add the Mayor of the District of Columbia to those eligible officials. The bill has no specified funding requirements or implementation timeline. By expanding the flag protocol, the measure treats the D.C. Mayor similarly to state governors in terms of official recognition when the position becomes vacant due to the officeholder's death.
