President Donald Trump and the national press corps are pushing to quickly revive the White House Correspondents’ Association dinner after Saturday night’s attempted shooting, but the effort is already running into the logistical and security challenges of staging one of Washington’s largest annual events.

Trump called for the dinner to be rescheduled within 30 days after an alleged gunman stormed the Washington Hilton. But that timeline is colliding with reality: The annual dinner, which draws more than 2,000 attendees, takes months to plan. So far, there is no proposal for how — or even whether — the event will return in its traditional form.
