Michelle Obama and Jill Biden Work the Food Bank

First lady Michelle Obama kept her promise to actively volunteer in the Washington area Wednesday, bagging lunches for hungry children at a local food bank on her husband's 100th day in office.

Mrs. Obama and Jill Biden, wife of Vice President Joe Biden, joined more than 100 congressional spouses at the Capital Area Food Bank on Wednesday, passing out packages of wheat pasta and cans of pineapple as volunteers bagged meals for low-income kids in the area.

The bags of food are expected to feed 1,000 children as part of a program that serves bagged to-go lunches to families on the weekends in lieu of free lunches at school. Each bag includes a variety of healthy foods and a recipe book and is designed to feed a child for five meals. MSNBC
