Former Democratic Congresswoman Debbie Halvorson announced on Monday that she will seek the Chicago-based House seat being vacated by Rep. Jesse Jackson, Jr. (D-IL), CBS News reports.

Halvorson represented a Chicago-area district for one term in Congress before she was defeated by Rep. Adam Kinzinger (R-IL) in 2010. She also unsuccessfully challenged Jackson in a Democratic primary this year. Jackson announced his resignation last week to treat his bipolar disorder. A special election has not yet been scheduled.
