Transcript for Malia and Sasha Obama: A Look Back
And finally tonight, malia and sasha obama are now 14 and eleven, growing up so fast. Malia started high school this week. So today we showed mrs. Obama photos. Her husband first sworn in as senator in 2005. Oh, my goodness, this was barack becoming a u.S. Senator. I remember this so clearly. See sasha there. She walked up to vice president cheney and she reached out her hand, she slapped him a high-five, ten turned around and waved at the camera, and i thought, oh, my god, here we go. But then suddenly, it's four years later, a presidential campaign and the first nomination. Oh, my goodness, the kids have gotten so big. I think that's what we look at. We don't look at the moment. We really measure things by how much the girls have grown. Daddy, what city are you in? This was convention 2008 in denver. I love you, daddy. And tonight, another convention, 2012. Two young girls, who've grown up in the white house, sasha now 11, malia, 14. We can see the physical difference. We can see the height. But what's the other most surprising change in them? I am pleasantly surprised at how normal they are. I did worry what this life would be like for them. Could I keep them normal? Could we instill in them the values that we learned growing up, humility, and decency and treating people with respect. And they are wonderful, young women, and we are so proud of them. They are level-headed, they work hard, they care about people. They're just good, solid kids.
