Jesse Jackson Jr. Has a Physical & EMOTIONAL Ailment? What, exactly, is that?

OK, what's really going on with Jesse Jackson Jr.? This "emotional ailment" release is very interesting. Is that professional barb for what your mama used to call a "nervous breakdown", "crazy"... "off the deep end"?

Rep. Jesse Jackson Jr. is struggling with physical and emotional ailments that will require extensive medical treatment, his office announced Thursday.

The statement, which comes after the Chicago Democrat took a medical leave of absence last month, said his condition is more serious than previously believed. His office initially attributed his medical leave to exhaustion.

"Congressman Jackson's medical condition is more serious than we thought and initially believed,” Jackson’s office said in a statement. “Recently, we have been made aware that he has grappled with certain physical and emotional ailments privately for a long period of time.”

The statement said Jackson is being evaluated and treated at an in-patient medical facility. It added that he will need “extended in-patient treatment as well as continuing medical treatment thereafter.”

The statement did not disclose the nature of his condition.

It also did not address if and when he plans to return to his congressional office.

Jackson is the target of a House Ethics Committee probe involving allegations that he was in talks to raise money for then-Illinois Gov. Rod Blagojevich in exchange for President Obama’s vacant U.S. Senate seat.
