The Secret Service said the man approached a checkpoint near 17th Street NW and Pennsylvania Avenue NW, pulled a firearm from a bag and fired at officers. Secret Service Uniformed Division officers returned fire, striking the suspect, who was later pronounced dead at a hospital. A bystander was also wounded, though officials said it was not immediately clear whose gunfire caused the injury. No Secret Service personnel were injured. Journalists on the White House North Lawn were ordered indoors and sheltered in the press briefing room as shots were heard nearby.
