NEW YORK (AP) -- The results of an auction just might put a fork in the mini-flap over New York Mayor Bill de Blasio's decision to use cutlery to eat pizza at a Staten Island restaurant. A charity auction website shows the fork that he used sold for $2,500 to an anonymous bidder. The item fetched six bids in an online auction that ended Friday. Proceeds will benefit the Stephen Siller Tunnel to Towers Foundation. The group helps first responders and wounded soldiers. Foundation Chairman Frank Siller tells the Daily News that the winning bidder gave the fork back to Goodfella's Pizzeria. Pizzeria co-owner Marc Cosentino tells news site DNAInfo "it's a nice piece of New York history to have." The mayor has taken jabs over his utensil usage lightheartedly.
