SUSPECT IDENTIFIED: Gunman who believed he was Jesus Christ opened fire on White House checkpoint, neutralized by Secret Service.

Nasire Best, 21, fired at a checkpoint at about 6:10 p.m. after being seen pacing in a strange manner up and down 17th St. Northwest, sources told The Post. He used a revolver and only got off a few shots before he was quickly shot and killed in a hail of bullets from federal officers.

A least one bystander was hit and seriously wounded in the fusillade, the sources said.

Exit quote: “While a motive for the attack hasn’t been confirmed, sources said Best is a mentally troubled individual who believed he was Jesus Christ and is known to the Secret Service and has violated a previous court order to stay away from the White House.”
