Ellen Thielman, a disabled veteran who suffers from knee and shoulder issues, witnessed the moment alleged White House Correspondents' Dinner shooter, Cole Allen, was taken down by the Secret Service after he attempted to enter the ballroom at the Washington Hilton's ballroom. Thielman witnessed the dramatic takedown of Allen, who was wearing magazines with bullets in them, and was yanked under a table and covered in a phone call to her son. She is grateful that no one was killed and that the unity before and after the shooting was restored, Thielman said. Allen is set to be arraigned on charges of wielding a firearm during a crime of violence and assault on a federal officer using a dangerous weapon.
