DES MOINES, Iowa - May 14, 2011 - Charges were dismissed Friday against executives with an Iowa gaming company who were accused of violating the state's campaign disclosure laws.

Peninsula Gaming LLC's chief executive Martin Brent Stevens and chief operating officer Jonathan Swain had been accused of making illegal campaign contributions to former Gov. Chet Culver's 2010 re-election campaign by donating money in another person's name.

At issue was a $25,000 campaign contribution to Culver, who donated the contribution to charity after questions were raised in the case.

The charges were dismissed in Polk County District Court after a special prosecutor filed a motion to do so, saying additional information was obtained indicating there was insufficient evidence to show the men violated the law.

Guy Cook, an attorney for Dubuque-based Peninsula Gaming and its executives, told The Associated Press that he and his clients were "convinced from the start that no crime was committed."

"Today's dismissal vindicates the company and its officers and reinforces Peninsula Gaming's reputation as a responsible and ethical company," Cook said.
