Rep. Jesse Jackson Jr. (D-IL) will resign his seat in Congress, the Chicago Sun-Times reports. Over the last several months, Jackson has been staying at the Mayo Clinic in Minnesota while coping with mental health problems. His reported maladies include “bipolar depression and gastrointestinal issues,” but the Congressman has been relatively private about his illnesses. His hospitalization coincided with an ongoing investigation into what was suspected to be inappropriate use of campaign funds. Jackson was also under an ethics investigation by Congress. In September, Jackson sold his home in Washington to help pay his medical bills. Despite being absent from the public eye, the nine-term Congressman handily won re-election to his tenth term this month.
