Democratic U.S. Senate hopeful Michelle Nunn returned to her volunteer roots on Saturday as she and Jill Biden volunteered at the 25th Hands on Atlanta Day service project.

Nunn, who founded the Hands on Atlanta volunteer organization, was joined by Biden, wife of Vice President Joe Biden, on a cloudless day in downtown Atlanta. Together the pair helped spread mulch and beautify a park on Boulevard after a rally at Fort Street United Methodist Church, while other volunteer teams spread out across the neighborhood.

While in Atlanta Biden will help raise money for Nunn’s campaign against Republican David Perdue, but Saturday’s event was decidedly non-partisan. The words “Perdue,” “Senate,” “Democrat” and “Republican” were never uttered.
