State Representative Keith Ellison of Minneapolis has won the Democratic endorsement for Congress in Minnesota's Fifth District. Delegates endorsed Ellison to succeed retiring Congressman Martin Sabo, who has held the seat since 1978. If elected, Ellison would be the first African American Congressman in Minnesota history. But the endorsement doesn't guarantee that he'll be DFLer on the November ballot because several Democrats say they'll run in a September primary. MPR’s Tom Scheck reports from DFL convention.
