The U.S. Secret Service has discovered a bullet that was fired at the White House, breaking through a pane of glass before being stopped by a second pane of ballistic glass.
Authorities are investigating whether the bullet was fired in an incident last Friday when shots were heard several hundred yards away from the White House near the National Mall.
After Friday evening’s shooting, police discovered an abandoned vehicle near the Theodore Roosevelt Bridge and the Lincoln Memorial. An AK-47 assault rifle was found in the car, according to multiple news sources.
Park Police issued a warrant for the arrest of Oscar Ortega-Hernandez, 21, based on the evidence allegedly found in the vehicle.
The Secret Service is investigating Ortega-Hernandez — who has not been detained for questioning — for any possible threat he might pose to President Obama. He has an arrest record in three states and is believed to be living in the D.C. area.
Obama and the first lady were not in any danger from the shooting. They had traveled to California last Friday and have flown to Hawaii and Australia since.
