Attending an event about the school's Black history program in partnership with the National Park Service, Emhoff was removed from the school's history museum by a Secret Service agent at 2:18 p.m., just five minutes after he arrived. Nadine Smith, the school's principal, followed shortly thereafter.

Teachers and students also later evacuated, and the incident is reportedly being handled by Secret Service. Smith said that students were dismissed for the day since it will take hours for Secret Service to sweep the building.
