For the past three weeks, Northwestern University student Anthony Ehlers has been painting a portrait of Mayor Brandon Johnson. Ehlers has been working on the painting, which depicts the mayor signing an executive order concerning the National Guard, in anticipation of Johnson’s visit on Sunday to Sheridan Correctional Center, where Ehlers is incarcerated. “He’s here on a Sunday when he usually is at church with his family; that’s pretty meaningful,” Ehlers said.
