The Rev. Jesse Jackson says his congressman son has checked back into the Mayo Clinic for an evaluation.
The elder Jackson told The Associated Press that Congressman Jesse Jackson Jr. was back at the Minnesota facility Tuesday. He was released from there last month following treatment for bipolar disorder and gastrointestinal issues.
A Mayo spokesman and Jackson's office didn't immediately have an update.
The congressman's father says the evaluation may lead to a longer stay. Congressional colleagues who visited the younger Jackson Monday say he was preparing for a longer visit.
Jackson took medical leave in June. His staff has released few details about his condition and hasn't said when he'll return to work.
Jackson is on the Nov. 6 ballot although he hasn't campaigned beyond a robocall to voters.
