CHICAGO – Gov. Pat Quinn on Sunday became the latest high-profile Illinois Democrat to back the candidate running against expelled state Rep. Derrick Smith.

Quinn and Secretary of State Jesse White – who was once a Smith supporter – appeared at a news conference on the city's West Side to back Chicago attorney Lance Tyson, a candidate chosen by Democrats after Smith was indicted on federal bribery charges and refused to step down.

"When we elect someone to office they must have an ethic of service, and that's what Lance Tyson is all about," Quinn said at the event held at a senior center.
