the hotel where the White House Correspondents' Dinner was being held on Saturday night. The 31-year-old suspect, who described himself as a mechanical engineer, game developer and teacher, is from Torrance in the Los Angeles region of California. He is due to appear in court on Monday. Police said Allen exchanged fire with security agents on a level of the Washington Hilton hotel that was one floor above the room in which Trump had gathered with members of his cabinet and journalists. After he was detained, Allen told officials he wanted to shoot officials in the Trump administration, two sources told CBS, the BBC's US news partner. US media are reporting a history of anti-Trump social media posts from 31-year-old Allen, citing law enforcement sources. (BBC)
