(CNN) – A top aide to embattled New York Gov. David Paterson has resigned his post.
Peter Kauffmann, Paterson's communications director for over a year, said in a statement, "I cannot in good conscience continue in my current position."
Kauffmann's resignation comes a day after New York's Commission on Public Integrity charged Paterson with an ethics violation for accepting free tickets to the first game of last year's World Series. The commission also said Paterson lied under oath about intending to pay for the tickets.
The governor, appointed after ex-Gov. Elliot Spitzer resigned in March 2008, announced last week he was forgoing a bid for his own term after media reports alleged he was involved in pressuring a woman to drop a domestic violence charge against an aide.
"I have been honored to serve the people of New York during a difficult time in our state's history. As a former officer in the United States Navy, integrity and commitment to public service are values I take seriously," Kauffmann also said in the statement.
Kauffman, a former consultant with the Washington, D.C.-based Glover Park Group, signed on with Paterson in February 2009 after the governor was criticized over his handling of the state's vacant Senate seat.
