Beau Biden, Delaware's attorney general and son to Vice President Joe Biden, made his father cry when he formally nominated him for reelection on the final night of the Democratic National Convention.
"It is my great honor to place into nomination for the office of vice president the name of my father, my hero, Joe Biden," Beau said.
CSPAN cameras captured Joe Biden wiping tears from his eyes and covering his mouth as he got choked up.
"I know Joe must be emotional right now. Your son calls you a hero, you gotta feel it in the heart," Los Angeles Mayor and DNC Committee chair Antonio Villaraigosa remarked.
