CHICAGO — Illinois Attorney General Lisa Madigan says she'll seek another term instead of running for governor next year.

In a statement Monday, the Chicago Democrat says she considered mounting a challenge to Gov. Pat Quinn, a fellow Democrat, but decided to stay in her current job and to seek re-election.

Madigan says one factor in her decision is that her father is the powerful speaker of the state House. She says the state would not be well-served with a governor and speaker from the same family.

Madigan's exit leaves former White House chief of staff Bill Daley, who's formed an exploratory committee to challenge Quinn, and four Republicans. Illinois faces major financial challenges, including a $97 billion hole in its pension funding.
