Obama was campaigning for Hillary Clinton in Fayetteville, North Carolina, when the incident

President Barack Obama told a rowdy crowd that they needed to show an elderly Donald Trump supporter who appeared to be a veteran some 'respect' today as they interrupted his remarks to scream at the man.

'Hey,' Obama said several times, trying to get his audience back. 'Listen up.'

As rally-goers continued defy him, Obama grew angrier and angrier, eventually demanding that attendees of the Hillary Clinton campaign event sit down and shut up.

'Hey everybody, hey,' he said, trying again. 'I told you to be focused, and you're not focused right now. Listen to what I'm saying.'

The man holding up the Trump for president yard sign had two patches on his jacket that signified that he was a member of the 101st Airborne

One represented the 'Screaming Eagles.' The other was an Airborne Special Forces patch. On his other breast he sported a Purple Heart, Bronze Star and what looked to be a Commendation Medal

Obama told the audience, 'You've got an older gentleman who is supporting his candidate. He's not doing nothing. You don't have to worry about him'

He told them to 'hold up' a few more times before he furiously demanded that 'everybody sit down and be quite for a sec.'

'Now listen up. I'm serious, listen up. You've got an older gentleman who is supporting his candidate. He's not doing nothing,' Obama proclaimed. 'You don't have to worry about him.

He said, 'This is what I mean about folks not be being focused.'

'First of all...hold up, hold up,' Obama said. 'First of all, we live in a country that respects free speech.'

'Second of all, it looks like maybe he might have served in our military, and we've got to respect that.

Continuing to scold them, Obama said, 'Third of all he was elderly and we've got to respect our elders. And fourth of all, don't boo...'

'Vote,' the Fayetteville, North Carolina, audience said, finishing his signature chant.

Back in control of rally, Obama told, 'I want you to pay attention. Because if we don’t, if we lose focus, we could have problems. This is part of what’s happened here during this election season.

'We just get stirred up for all kinds of reasons that are unnecessary,' he said to laughter. 'Just relax.'

Obama used the moment to shame Trump for fights he's started with various veterans

Obama used the moment to shame Trump for fights he's started with various veterans.

'We can't afford a Commander-in-Chief who insults POWs, who attacks a Gold Star mother, who actually talks down our troops, says he knows more than our generals,' Obama said.

The outgoing president recalled his first day on the job.

'I had to sit down with somebody who explained this whole nuclear thing. It will sober you up,' he said. 'It’s serious business.'

Bashing Trump, Obama said, 'We can't have somebody like that handling our nuclear codes. We can't have somebody who gets upset because “Saturday Night Live” does a skit about him and starts tweeting at three o’clock in the morning.
