After delivering an address in Denver in July, Vice President Joe Biden was shaking hands with members of the audience when someone yelled out to him.
"Maj. Beau Biden. Bronze Star, sir. Served with him in Iraq," the man said, Biden recalled Thursday during an interview with Stephen Colbert.
"I was doing great," Biden continued. But then, "I lost it. You can't do that.”
It's been more than three months since Biden lost Beau, his eldest son, to brain cancer, forcing the vice president to contend with personal tragedy in the public eye for the second time in his life.
