The director of the Secret Service, Kimberly Cheadle, has resigned amidst a harrowing incident that saw a gunman nearly assassinate a former president. Despite a robust security presence, the gunman managed to position himself on a rooftop, an act that has sent shockwaves through the nation. Cheadle, however, stood resolute against bipartisan calls for her resignation until Monday.
