Michelle Obama had this to say: “You see, when we said we wanted to host a concert to honor our military kids, let me tell you, everyone wanted to be here. Usher wanted to be here, Katy Perry wanted to be here. Nick Cannon, the folks from Glee, and all the other amazing performers — they wanted to be here, too. And let me tell you, they’re not here for me. They’re not here for Dr. Biden. They are here for all of you. Because they know the kind of sacrifices that you all make every single day.”
