It looks like Jesse Jackson Jr. isn't an addict after all. Rumors about the congressman and son of Rev. Jesse Jackson were swirling furiously yesterday after reports of him entering a rehab facility in Arizona. But Jackson's doctor stated that his patient was "receiving intense medical treatment at a residential treatment facility for a mood disorder. He is responding positively to treatment and is expected to make a full recovery." Initial reports claimed that Jackson was receiving treatment for drug addiction, while NBC's Andrea Mitchell tweeted that he was in the facility for alcoholism. The congressman went on medical leave from his position on June 10, but didn't announce his decision until two weeks later. His office released a statement last week that he was being treated at an inpatient medical facility for "physical and emotional ailments" that are "more serious" than initially believed, but House Leader Nancy Pelosi repeatedly called for an update on Jackson. He is still under an ethics investigation related to Illinois' imprisoned former governor Rod Blagojevich, but has yet to be charged with any wrongdoing.
