Former White House chief of staff running for Illinois governor

Former White House chief of staff Bill Daley is making his Illinois gubernatorial bid official.

He's set to remove his "exploratory committee" label Tuesday by filing paperwork with the Illinois Board of Elections. So far, he's Gov. Pat Quinn's only 2014 Democratic primary challenger.

In a video on his campaign website, Daley says the fact that the state Legislature adjourned in May without finding a solution to the pension crisis or voting on same-sex marriage represents a "dysfunction."

He says he's running because of the positive response he's received and he'll work seven days a week.

The brother and son of two longtime Chicago mayors formed his exploratory committee last month, but has already been acting like a candidate.

He's stepped out to criticize Quinn's leadership and made statewide tours.
