However, Kevin Lampe says in a statement that Jackson won’t hold an election night event next week.

Jackson has been at Minnesota’s Mayo Clinic for treatment for bipolar disorder. He recently checked in for the second time and there’s been no indication of when he’ll return to work.

The Chicago Democrat took medical leave in June and hasn’t campaigned beyond a recent robocall to voters. In it, he asked for patience and says he wants to return to work.

Jackson first took office in 1995 and is widely expected to win again Tuesday. He faces two little-known challengers on the Nov. 6 ballot, including a Republican college professor and postal worker running as an independent.
