CHICAGO (AP) -- Congressman Jesse Jackson Jr. has left the Mayo Clinic, but it isn't clear where he's heading or if he plans to return to work in Washington.
Congress is in session and votes are scheduled for Tuesday night.
But Mayo spokesman Nick Hanson says he didn't know where Jackson was going after leaving the clinic, and people close to the 47-year-old Democrat didn't immediately return phone calls.
Jackson was being treated at the Minnesota clinic for bipolar disorder.
He recently was elected to his ninth term, despite reports that he faces a new federal investigation into potential misuse of his campaign finances.
The Chicago Sun-Times, citing anonymous sources, first reported the probe. It is reportedly separate from a House ethics committee investigation into Jackson's connections to imprisoned ex-Illinois Gov. Rod Blagojevich.
