One of the greatest moments of the day Ret. Army Specialist Cody Full gave testimony at Congress, was when he interrupted U.S. Rep. Brad Sherman (D-Calif).

The Congressman was trying to ask a doctor what conditions were like to make someone walk away - trying to justify the AWOL when Full said "Can I have permission to speak?" The interruption takes place at 1.42, but you should watch the whole thing to see how Sherman treats a Republican.
