The office of embattled Illinois Representative Jesse Jackson, Jr. today released a statement that the medical condition keeping Jackson from office “is more serious than we thought and initially believed.”

Jackson, citing exhaustion, has been on a leave of absence since June 10. He is under investigation by the House Ethics Committee in connection with the alleged sale of President Barack Obama’s former U.S. Senate seat by former Illinois Governor Rod Blagojevich.

Thanks to the unspecific and somewhat secretive nature of the statement, it didn’t take long for the Twitterverse to wonder if Jackson’s “exhaustion” was of the kind most often associated with Hollywood celebrities.

Any post that begins with “word on the street” should be taken with a very large grain of salt. “Mystery” is more like it, but who needs more mystery in politics, especially when an ongoing investigation is involved? Less mystery, please.

Some find it hard to question the timing. The statement reportedly makes no mention of a timetable for Jackson’s return and extends his leave indefinitely.
