(AP) -- The Rev. Jesse Jackson says his congressman son's treatment at the Mayo Clinic for depression is a "game changer."
The elder Jackson spoke to reporters about U.S. Rep. Jesse Jackson Jr. on Saturday outside a Chicago movie theater. The civil rights leader was with protesters supporting an assault weapons ban. Jackson said there is no timetable on his son's recovery and asked for prayers for their family.
The younger Jackson has been on a secretive leave of absence for nearly seven weeks. The Mayo Clinic in Minnesota said Friday the congressman was being treated there for depression and gastrointestinal issues.
Jackson is facing an ethics investigation in the U.S. House connected to former Illinois Gov. Rod Blagojevich, who was convicted on corruption charges. Jackson has repeatedly denied wrongdoing.
