Walker Leaves WUSN: Audacy WUSN/Chicago midday host Drew Walker has departed the station after 20 years for an as-yet-undisclosed opportunity. His last show was yesterday (5/2). He started at the station as afternoon driver in 2004. Calling his time at WUSN "one of the great joys of my life," Walker says it's "time for a change, and although I'm not allowed to speak about any of it yet, I'm so excited for my next chapter here in Chicago. It's going to be good." Reach him here.
