A state audit says Brooklyn Assemblyman William Boyland Jr. must repay the government $67,000 for false travel expenses.
The audit conducted by the state comptroller's office found he improperly filed for travel reimbursement to Albany more than 600 times between 2007 and 2012.
Lawmakers get up to $165 to cover their daily expenses when they travel to Albany.
The assemblyman didn't immediately respond to a request for comment.
The Democrat was indicted in December 2011 for allegedly taking bribes to help influence state contracts. A trial is set for July.
He was found not guilty in November 2011 on separate federal criminal charges in a wide-ranging corruption case.
