Biden referenced a recent Atlantic story that reported that Trump disparaged American troops, touching on his own son’s service.

“He was not a loser, he was a patriot and the people left behind there are heroes,” Biden said of service members including Beau Biden, his son who died in 2015 from cancer and served in Iraq.

“I don‘t know Beau, I know Hunter,” Trump said, returning to a familiar line of attack. “Hunter got thrown out of the military.”
