Ben & Jerry's co-founders Ben Cohen and Jerry Greenfield took the stage at the Howard Theater in Washington, D.C. on Dec. 4 with Rev. Dr. William J. Barber II and Rev. Dr. Liz Theoharis to announce the ice cream makers' support of the Poor People's Campaign: A National Call for Moral Revival.

A portion of the proceeds from Ben & Jerry's new One Sweet World limited batch flavor will benefit the campaign's efforts to promote economic and racial justice, the Burlington, Vt.-based company said. After the announcement, Aloe Blacc, Maxwell, Sweet Honey in the Rock, JPeriod, Yara Allen, Gina Belafonte and Van Jones headlined the "We are Here" concert presented by Sankofa.org in support of the campaign.
