Transcript for Proud dad cheers on his daughter
Finally tonight here, America strong. The high school cheerleader and her very, very proud dad. This dad warming up, fourth quarter, York hill versus warhill high. His favorite cheerleader, his daughter, taking the field. And dad's watched so many times, he knows the York high cheer. That dad and his daughter, she's 15. When she looks up in the stands, she sees him and his every move. He knows when the pom poms go up and he can kick. And he certainly cheers. Leading the crowd, too. Go falcons. Go falcons! Reporter: And it turns out, daughter Mackenzie taught him the routine when the falcons score a touchdown. He's been practicing for weeks now. Tonight, taking a break from that practice. Hi, David. Go falcons! Reporter: We couldn't help but notice his sweatshirt says "Everything hurts." Those workouts. And what does Mackenzie make of it all? She says he's not embarrassing, saying his moves sometimes sharper than hers. And by the way, that night in the stands? The falcons won. So did dad. Go falcons. Thanks for watching here on a Thursday night. I'm David Muir. I hope to see you right back here tomorrow. Good night.
