U.S. Rep. Jesse Jackson Jr. has been released from the Mayo Clinic, a spokesman confirmed on Tuesday. Jackson had been receiving his second treatment for bipolar disorder in months. The news comes on the heels of rumors that a federal investigation of the congressman’s misuse of campaign funds may now be extending to his wife. Jackson won reelection to a ninth full term of his 2nd district seat in Chicago despite making few campaign appearances due to his medical leave. Details of Jackson’s current whereabouts are unknown.
