Rep. Jackson Jr. checked into Mayo Clinic, says Rev. Jackson

Rep. Jesse Jackson Jr. (D-Ill.) returned to the Mayo Clinic on Tuesday, according to his father, the Rev. Jesse Jackson.

The elder Jackson told The Associated Press that the Illinois congressman had checked back into the Minnesota clinic on Tuesday. Jackson Jr. had previously been receiving treatment at Mayo over the summer for bipolar disorder before being released in September.

Rev. Jackson also told the AP that his son was currently being evaluated and, depending on the results of the evaluation, could stay for an extended period of time.

On Monday, two of Jackson Jr.'s colleagues in the Illinois congressional delegation, Reps. Danny Davis and Bobby Rush, both Democrats, visited Jackson Jr. in his home. At the time, Rush said the congressman "looks well, but he doesn't feel as well as he looks." 

In June, Jackson Jr. took a leave from Congress citing exhaustion. Months later, Jackson Jr.'s office revealed that he was suffering from bipolar disorder.

Despite ensuing speculation that he could step down from his seat, the Illinois Democrat has continued to run for reelection. A WeAskAmerica survey released Monday found him leading Republican challenger Brian Woodworth 58 percent to 27 percent.
