First lady Michelle Obama ate lunch with local students and star athletes Michael Phelps, Nastia Liukin and Justin Tuck at a D.C. Subway Thursday. At the event Obama announced that the restaurant chain will be joining the Partnership for a Healthier America (PHA) for its largest marketing campaign to promote healthier choices to children.

Hey, isn’t that…Olympian gold medalist Michael Phelps, getting patted down by heavy security on his way into the Subway sandwich shop on 17th and L Streets, NW.

The extra caution surrounding the suit-clad swimmer wasn’t business as usual. Subway, whose windows were covered in paper, according to our tipster, is likely the site of an announcement today with first lady Michelle Obama of an initiative to add healthier choices for kids to the chain’s menu, a move first reported by the AP.

Phelps is a Subway pitchman and a Towson, Md., native.
