VP Joe Biden Unleashes Stern Criticism of 'Ignorant' Donald Trump's PTSD Remarks

"He's not a bad guy, but how can he be so out of touch," the VP asked.

Watch the second presidential debate, co-moderated by ABC News’ Martha Raddatz, on ABC News and ABCNews.com at 9 p.m. ET on Sunday, Oct. 9.

Biden said, “Over 200,000 coming home with unseen wounds. Twenty suicides a month. I don’t think he was trying to be mean. He is so thoroughly completely uninformed."

“When I went to pin [a Silver Star] on him in front of the entire brigade, he stood and looked at me and said, ‘Sir, I don’t want the medal. I don’t want the medal.’ You know why? He said he died. ‘He died, Mr. Vice President. I don’t want the medal.’ How many nights does that kid go to sleep seeing that image in his head, dealing with it?” Biden said.

“[Trump] is an ignorant man. This guy says things he has no idea, but he's not a bad man. But his ignorance is so profound. So profound,” Biden said. “What's this say about a guy who doesn't have any notion of that? Look at what these kids are going through. Look at the sacrifices they're making. And look what they go to sleep dreading.

“That [captain] probably goes to sleep every night with a nightmare. And this guy [Trump] doesn't understand any of that? How can he not understand that?” Biden said sternly, growing visibly angry.

“How can he be so out of touch? He's not a bad guy, but how can he be so out of touch, and ask to lead this country?”

During the Clinton rally, the vice president repeated his mantra that the most sacred obligation the United States has is “to care for those we send to war and to care for them and their families when they come home.”

“What are the chances this guy will honor that commitment?” Biden asked of Trump. “I’m serious about it. It’s not that he just doesn’t get it. He has no interest in finding out.”
