FILE - In this March 20, 2012 file photo, U.S. Rep. Jesse Jackson Jr., D-Ill., his wife Chicago Alderman Sandi Jackson, and their children Jessica, 12, and Jesse III, 8, thank supporters after his primary election win over challenger, former Rep. Debbie Halvorson in Illinois' 2nd District. When Jackson disappeared on a mysterious medical leave in June 2012, it took weeks for anyone in Washington to notice. Jackson has never lived up to the high expectations on the national stage. But none of that seems to matter in his district, where he’s brought home close to $1 billion in earmarks and other funding and won every election since 1995 in a landslide, despite nagging ethical questions over links to imprisoned former Gov. Rod Blagojevich. The dual roles could help explain why the Democrat has given so few details of his medical leave. (AP Photo/M. Spencer Green, File)
