Anne has been following the bizarre Jesse Jackson, Jr. saga for months, and has noted that the medical excuses and disappearing act likely was hiding some other problem

When The Chicago Tribune refused to endorse Jackson, it was clear something was brewing.

Now we know what, via The Chicago Sun Times, Feds probe ‘suspicious activity’ in Jesse Jackson Jr.’s finances:

Spelling potentially new trouble for U.S. Rep. Jesse Jackson Jr., federal investigators have launched  a probe into the South Shore congressman’s finances — a completely new area of scrutiny, sources told the Chicago Sun-Times.

The investigation — based in the Washington, D.C., FBI field office — is not related to the attempted sale of the U.S. Senate seat that figured in former Gov. Rod Blagojevich’s corruption conviction, but is focusing on  “suspicious activity” involving the congressman’s finances related to his House seat and the possibility of inappropriate expenditures, sources said.

The probe was active in the weeks prior to Jackson taking a leave from his U.S. House post on June 10, a leave his office ultimately attributed to his need for treatment for a bipolar disorder, the sources said.

Bonus question:  Will voters in his district care?
