Gov. Pat Quinn has blasted a new commercial by his Republican opponent in which headlines from news stories appear doctored.

Speaking to reporters at a Thursday campaign event in Chicago, the Democrat called the alterations "clearly wrong."

Bruce Rauner's 30-second commercial called "Headlines" overlays what appear to be newspaper headlines over images of Quinn. The headlines criticize Quinn's record on jobs, schools and a troubled anti-violence program. But a review of the ad reveals several cases where the purported headlines don't match the headlines media outlets actually used.

Citing the ad, Quinn told reporters Thursday his challenger has displayed "a pattern of dishonesty" during the closely contested race.

Rauner's campaign says the phrases in the commercial were simply condensed because of time and space constraints.
