President Obama authorized the action in a proclamation this afternoon. He calls it “a mark of respect for the victims of the senseless acts of violence perpetrated on July 20, 2012, in Aurora, Colorado.” The order applies to U.S. flags flown on government and public grounds and runs until sunset July 25.
