CHICAGO | The mystery surrounding U.S. Rep. Jesse Jackson Jr.'s leave of absence deepened Thursday as his office disclosed a few more vague details about his medical condition, saying his ailments were "more serious" than previously thought and he needs extended inpatient treatment.
But his staff gave no hint of the congressman's whereabouts or exactly what he was suffering from, saying only that he has grappled with physical and emotional problems "privately for a long period of time" and was at an in-patient facility.
The nine-term Chicago Democrat has come under intense scrutiny in recent years for ties to imprisoned former Illinois Gov. Rod Blagojevich and an extramarital affair. Despite a pending U.S. House ethics investigation connected to Blagojevich, he has been widely expected to win re-election in November.
He has been on medical leave for three weeks, though his office didn't disclose his leave until last week — and did so in a meager three-sentence statement saying he was being treated for exhaustion. Neither his family nor his staff has offered more explanation, and the statement Thursday provided few details.
"Congressman Jackson's medical condition is more serious than we thought and initially believed," the statement said. "Recently, we have been made aware that he has grappled with certain physical and emotional ailments privately for a long period of time. At present, he is undergoing further evaluation and treatment at an in-patient medical facility."
The statement said Jackson, 47, will need "extended in-patient treatment as well as continuing medical treatment thereafter."
Multiple messages left for his spokesmen, his brother and his wife, Chicago Alderman Sandi Jackson, were not returned. His father, the Rev. Jesse Jackson, said he spoke to his son once recently and he sounded "exhausted and overwhelmed."
"He'll be in for a longer stay for more evaluations and treatment of his challenges," the civil rights leader said, declining to elaborate.
The news of Jackson's illness has baffled congressional colleagues. They noted his absence on the House floor in previous weeks, but several said they have not heard from him at all.
"No one has a clue," said U.S. Rep. Mike Quigley, a fellow Illinois Democrat. "There is concern among his colleagues. ... Anybody there could understand that. It's a stressful occupation."
In order to take a medical leave of absence, Jackson must notify the leader of his party's House delegation in writing. A spokesman for Democratic Leader Nancy Pelosi, D-Calif., did not immediately respond to multiple requests for comment Thursday. Michael Steel, a spokesman for House Speaker John Boehner, R-Ohio, said his office had not received any notification from Jackson's office.
Jackson, who first won office in 1995, is facing a House Ethics Committee investigation over allegations that he was involved in discussions about raising money for Blagojevich's campaign in exchange for the then-governor appointing him to President Barack Obama's vacated U.S. Senate seat.
Jackson also allegedly directed fundraiser and longtime friend Raghuveer Nayak to buy plane tickets for a woman described as Jackson's "social acquaintance." Jackson has since called the incident a personal matter that he and his wife have dealt with.
Nayak was arrested last month and pleaded not guilty to unrelated fraud charges involving outpatient surgery centers he owns. At Blagojevich's first corruption trial in 2010, prosecutors said another Blagojevich fundraiser was ready to testify that Jackson instructed Nayak to raise money for Blagojevich's campaign to help him secure the Senate seat. The same witness later testified that he attended a meeting with Jackson and Nayak.
Jackson never has been charged and has denied any wrongdoing. But he's had to repeatedly defend himself, especially on the campaign trail in recent years.
