LAWRENCE, Kan. (AP) - The mayor of Lawrence has resigned his position leading a local food bank that owes $50,000 in federal payroll taxes. The Lawrence Journal-World reports that Mayor Jeremy Farmer has stepped down from his position as executive director of Just Food. Farmer says Just Food recently discovered that several payroll tax payments had not been made, and the missed payroll taxes are part of the reason for his resignation. He denies any intentional wrongdoing. Kristi Henderson, president of Just Food's board of directors, confirmed that the nonprofit group has about a $50,000 federal tax liability. She says the board is investigating whether Just Food owes any Kansas state taxes. Henderson says there's no indication money was misappropriated, and the problem appears to be a lack of attention to detail.
