During President Obama's speech to veterans in Pittsburgh Tuesday, several retired veterans got into a tussle when one tried to protest the president's speech with a Benghazi sign in hand.

NBC News reported that one elderly veteran lifted a sign reading "The emperor Benghazi has no clothes" and was immediately assaulted by several  other former military men.

The elderly veteran protesting was thrown down onto the back of his chair as the other veterans ripped his sign away from him. In the end, he didn't look seriously injured and stood up raising his hands in further protest.

The sign referenced to the September 11, 2012, attacks on the U.S. diplomats in Benghazi, Libya which resulted in the death of four Americans, including Ambassador Christopher Stevens.
