CHICAGO – The wife of former U.S. Rep. Jesse Jackson Jr. announced Friday that she was resigning from the Chicago City Council, saying she could not adequately represent her district while dealing with "very painful health matters."

Alderman Sandi Jackson, whose husband recently resigned from Congress while being treated for bipolar disorder and other medical issues, said in a letter to Mayor Rahm Emanuel that her resignation would be effective Tuesday.

"I am unapologetically a wife and a mother and I cannot deny my commitment to those most important personal responsibilities," she wrote. Aside from citing health matters, she did not elaborate.
