WASHINGTON — Rainbow Push Coalition president Rev. Jesse Jackson told The Daily Caller Friday that Sen. Bernie Sanders was active in the Civil Rights movement in Chicago.

“Bernie was fighting back in Chicago not in the deep-south — in affordable housing struggles in Chicago. The movement was so broad based. There were civil rights leaders in Chicago,” Rev. Jackson said, confirming it might be too quick to dismiss Sanders’ activist background.

The Congressional Black Caucus PAC, though, endorsed Clinton on Thursday, a move that upset CBC member and Sanders supporter Minnesota Rep. Keith Ellison . Jackson, himself, wondered if the PAC’s endorsement was a good idea.

“My concern there is, they’re choosing based on relationships…my concern is what is the agenda? What does the agenda need? Who has the most immigrant and figures plan for affordable health care — accessible affordable education and job training and housing re-construction and urban development? That’s what we need. Something needs to be built around that,” Jackson said.

He added, “[Their endorsement] is based on their interests… My focus has been based on voter registration and issue development. That’s what I’m focused on.”
