On this week's episode of the Under the Dome podcast, we review the festivities surrounding the inauguration of Illinois Gov. J.B. Pritzker, including an appearance by Maroon 5, led by Adam Levine (pictured), the mystery headliner who played at the big inauguration party. We also talk about Pritzker's first week on the job, which included signing a gun-control bill and giving step raises to state employees.
