Jesse Jackson Jr.'s resignation from Congress might end his once-promising political career but it doesn't mark the end of troubles for the civil rights icon's son.
The nine-term Chicago congressman submitted his letter of resignation Wednesday. The letter confirms publicly for the first time that he's under a federal probe and cooperating with investigators. Jackson also admits that his health issues have kept him from returning to work as he wants.
Jackson's attorneys say it could be months before there's a resolution to the investigation.
Meanwhile members of the House Ethics Committee could decide to release a final report on what they found in their probe of Jackson's ties to ex-Illinois Gov. Rod Blagojevich.
