Michelle Obama

FILE – In this Feb. 27, 2014 file photo first lady Michelle Obama and a young student show off their muscles as they eat healthy snacks during a visit to La Petite Academy in Bowie, Md., to encourage healthy habits at preschool as part of her Let’s Move! Child Care program. First ladies typically avoid getting into public scraps, but Obama is in the biggest fight of her tenure as she pushes back against a House Republican effort to soften a key component of the anti-childhood obesity effort at the center of her legacy. And she says she is ready ìto fight until the bitter end,î if that is what it takes. (AP Photo/Carolyn Kaster, File)
