The Indiana mayor who shut down Chief Keef ‘s concert over the weekend went and mugged for the camera with rapper 2 Chainz … because he says Chainz is all about having a good time while Keef attracts a bad element. Hammond Mayor Thomas McDermott tells TMZ he pulled the plug on Keef’s non-live, hologram performance Saturday night because of Keef’s “anti-cop, pro-gang” lyrics. As for why McDermott took a pic 2 days later with 2 Chainz … he says the rapper’s lyrics are innocuous and the crowds are more chill.
