Beyonce is set to perform with husband and rapper Jay Z at a get-out-the-vote concert in Cleveland, Ohio, for Democratic presidential nominee Hillary Clinton Friday. CBS News reported the development, which the Clinton campaign didn't confirm. Ohio is a key battleground state, which GOP nominee Donald Trump currently holds by a small margin. The concert lineup already includes Katy Perry and John Legend. CBS believes it's a play to win over the area's young and African-American voters.
