CHICAGO (MCT) — Four months before the election, an aide to absent Rep. Jesse Jackson Jr. said Thursday the congressman’s physical and emotional illnesses are “more serious than we thought” and will require extended treatment.

But once again, Jackson’s camp gave no further details about the Illinois Democrat’s precise condition, treatment, location or expectations of returning to work. The congressman took a medical leave June 10 to be treated for what a spokesman said was “exhaustion,” but his office did not disclose that decision until more than two weeks later.
