The man who opened fire near the White House security perimeter on Saturday evening has been identified as 21-year-old Nasire Best from Maryland, according to multiple US media reports.
Best was shot and killed by Secret Service officers after he approached a checkpoint near 17th Street and Pennsylvania Avenue NW, removed a firearm from his bag and began shooting. A bystander was also injured in the exchange of gunfire. President Donald Trump was inside the White House at the time but was unharmed.
