It was recently revealed that the Democrat went on medical leave June 10 and was being treated for exhaustion. A statement released today by spokesman Frank Watkins suggests Jackson, first elected to the U.S. House in 1995, could be out for some time.
"Recently we have been made aware that he he has grappled with certain physical and emotional ailments privately for a long period of time," the statement said. "At present he is undergoing further evaluation and treatment at an in-patient facility."
Watkins said Jackson will need "extended in-patient treatment as well as continuing medical treatment."
Jackson, 47, is being investigated by the House ethics committee for allegedly raising campaign money for then-Illinois governor Rod Blagojevich in exchange for an appointment to the U.S. Senate seat once held by President Obama. Jackson has repeatedly denied any wrongdoing.
In March, the congressman easily defeated Debbie Halvorson in a Democratic primary. It was considered Jackson's strongest election challenge since taking office.
