Civil rights leader Jesse Jackson will join Bernie Sanders today at a rally in Grand Rapids, Michigan to officially endorse the Senator for president. In a statement, Jackson said:

“With the exception of Native Americans, African Americans are the people who are most behind socially and economically in the United States and our needs are not moderate. A people far behind cannot catch up choosing the most moderate path. The most progressive social and economic path gives us the best chance to catch up and Senator Bernie Sanders represents the most progressive path. That’s why I choose to endorse him today.”

ABC News writes: Sanders supported Jackson’s 1988 presidential bid and helped Jackson score a primary win in Vermont. Now, as concerns mount about Sanders’ ability to garner the support of black voters, Jackson is returning the favor.
