Rep. Jesse Jackson Jr. (D-Ill.) is positioning himself to run for reelection even as he receives medical treatment at the Mayo Clinic in Rochester, Minn.

Several Jackson aides told Crain's Chicago Business the nine-term lawmaker plans to run in November.

And Jackson's chief of staff, Rick Bryant, has been making calls to 25 mayors in the Chicago suburbs to update them on the lawmaker's condition.

Bryant told the paper he made the calls at Jackson's request.

"I told them that the congressman was feeling much better and that he was looking for updates on several projects in the district," Bryant said. "The congressman also said he expects to be home soon; he is looking forward to getting back to work; and he fully expects to be running for re-election in the fall."

Even so, family members say it remains unclear when Jackson will return to his regular duties. Jackson's father, the Rev. Jesse Jackson, said earlier this week that there's no timetable for when his son will be released.

"It's not the kind of health challenge that you can put on a timetable, but he is responding as he seeks to regain his strength," Jackson's father said.

The lawmaker is being treated for severe depression and gastrointestinal problems at the Mayo Clinic. He took a leave of absence from Congress in June.
