why is the american flag at half mast

The American flag is at half-mast from August 27 until sunset on August 31, 2025, as a mark of respect for the victims of a senseless mass shooting that occurred on August 27, 2025, at Annunciation Catholic School in Minneapolis, Minnesota. Two children were killed and at least 17 others were injured in this tragic event. President Donald J. Trump issued a proclamation ordering the flag to be flown at half-staff nationwide, including at public buildings, military posts, and U.S. embassies abroad, as a symbol of mourning and respect for the victims of this violence.
