Biden trips and falls during Air Force Academy graduation ceremony

President Biden tripped and fell on stage after congratulating the graduates of the U.S. Air Force Academy, but was helped up by officials and continued participating in the event. The president had been standing on the stage for more than two hours saluting recent graduates as their names were read out, and as the temperature in El Paso County, Colo., was in the 60s. Biden used part of his address to emphasize how far the country’s armed forces have come in terms of racial, ethnic and gender diversity.
