(CBS News) Rep. Jesse Jackson, Jr. has been on a medical leave of absence for more than two weeks, his office announced late Monday.
The statement released by the Illinois Democrat's office said he is "being treated for exhaustion" and has been on leave since June 10.
"He asks that you respect his family's privacy. His offices remain open to serve residents of the Second District," the statement said, without any further elaboration on where he was being treated or how long he is expected to remain out of pocket.
The statement released Monday was the first time his office revealed that Jackson was not working.
His office released a press release June 18 quoting Jackson hitting Republicans for "fiddling" while Americans are unemployed.
"I continue to believe that Republicans would rather see President Obama fail than see America succeed. This week's legislative agenda is the latest example. House Republicans are running out the clock on the economy at exactly the time we should be working around-the-clock to create jobs and strengthen the economy for all Americans," Jackson said in the statement released a week after he went on leave and a week before it was revealed he was out.
The Chicago Sun-Times reported that Jackson is in the midst of marital difficulties.
"I know he has been under a lot of pressure," the newspaper quoted a Jackson friend from Washington as saying, "he's been fighting really hard to save his marriage. And he had a tough election. There's been a lot of stuff."
Jackson is facing a congressional ethics investigation related to the corruption case of former Illinois Gov. Rod Blagojevich, a convicted felon who is now in prison after trying to enrich himself as he filled the Illinois Senate seat of President Obama after he was elected to the White House.
A key fundraiser in that case, Raghuveer Nayak, was arrested by federal authorities last week on unrelated charges. Jackson is a friend of Nayak.
Jackson's attorney, Paul Langer, told the newspaper that his medical leave is not tied to the Nayak case.
"I can tell you unequivocally it is unrelated to the arrest of Mr. Nayak," said Langer.
Another fundraiser for Blagojevich was reportedly ready to testify at the first corruption trial in 2010 that Jackson instructed Nayak to raise money for the governor's campaign in exchange for Mr. Obama's seat.
Jackson has denied wrongdoing and has not been charged.
