Bridges is the national spokesman for the No Kid Hungry campaign, an effort to pair private groups with federal anti-hunger programs to ensure more children have access to free food after school and during the summer.
The event, at Barcroft Elementary School, will also be hosted by the executive directors of Share Our Strength and the Federation of Virginia Food Banks.
The groups estimate that 218,000 Virginia children face hunger. They say only 18 percent of kids who qualify for free and reduced-priced lunches during the school year receive similar support during the summer.
The national No Kid Hungry campaign aims to eliminate childhood hunger in America by 2015.
