(CBS News) Rep. Jesse Jackson Jr., D-Ill., is currently being treated for a "mood disorder", his doctor's office said Thursday.

"The Congressman is receiving intensive medical treatment at a residential treatment facility for a mood disorder," a statement from his physician said. "He is responding positively to treatment and is expected to make a full recovery."

The office would not give any further information, including his doctor's name, citing privacy. 

"The name of the attending physician and treatment center will not be disclosed in order to protect his continuing privacy," the statement read.

The news comes after a growing number of his Democratic colleagues have called for the congressman to be more forthcoming about his recent weeks-long medical leave from Congress.

"The public relationship that he has as a member of Congress, I think does not shield him," Rep. Luis Gutierrez, D-Ill., said.

"I think Congressman Jackson and his office and his family would be well-advised to advise his constituents of his health condition," House Minority Whip Steny Hoyer, D-Md., told reporters Wednesday.

"His health is the number one priority," Sen. Dick Durbin, D-Ill., said. "As a public official though, there reaches a point where you have a responsibility to tell people what you're facing and how things are going."

Until Wednesday's news, the only statements on Jackson's condition were two vaguely-worded releases from his congressional office.

The first, in late June, said he was suffering from "exhaustion." But the second said his "medical condition is more serious that we thought" and that the 47-year-old congressman was receiving "extended in-patient treatment" after dealing with "certain physical and emotional ailments privately for a long period of time."

In the absence of any real information, rumors have begun to fly on Chicago talk radio, with some even speculating the congressman attempted suicide - a theory his inner circle has denied.

Rev. Jesse Jackson, the congressman's father said recently, "Rumors are flying, but we have to rely on the truth."

Like all House members, Rep. Jackson is up for re-election this year. His father says he does expect him to return to Congress and that he will give a full explanation about his condition and where he's been when he's doing better.

Rep. Jackson has been facing an investigation by the House Ethics Committee into whether he pressured a friend to raise millions for disgraced former Illinois Gov. Rod Blagojevich in exchange for Blagojevich naming Jackson to President Obama's former Senate seat. Jackson insists he did nothing wrong and, obviously, he wasn't named to that seat. But his friend was arrested a few weeks ago on unrelated federal fraud charges.

In addition, Jackson has reportedly been under some personal strain, but whether that strain has contributed to his condition is unclear.
