Chicago mayoral candidate Lori Lightfoot released the following statement in response to a Facebook comment in which Scott Cisek, a top adviser to mayoral candidate Toni Preckwinkle, posted a picture of Nazis at the Nuremberg Trials in an argument about whether to support Lightfoot.

“Politics is a tough business,” said Lightfoot. “I knew that before I jumped in. But it is disturbing to me that a mayoral candidate’s top adviser believes the genocide of millions of people is a casual enough subject to be used as a joke to settle a political argument. Take note of those that surround the people we expect to lead.”
