The shooting at the White House Correspondents’ Association dinner in Washington, D.C., on Saturday has the District on edge as it gears up for a summer of high-profile events marking the country’s 250th anniversary. 

The suspect, Cole Allen, accused of running through the dinner’s security checkpoint, shooting a Secret Service officer, and running toward the room where President Donald Trump and other high-profile attendees were gathered, was charged on Monday with attempting to assassinate the president.
