Sam Waterston has debuted as President Barnes on the NBC series Line of Fire. The episode reveals that an individual previously blamed for an assassination attempt against the President was actually innocent.
Why it matters
The storyline centers on new evidence regarding a six-year-old assassination attempt that suggests the official account was inaccurate. Secret Service agent Mike Hollingsworth has long maintained that the initial investigation into the shooting was flawed.
