Two suburban New York elected officials and the spouse of one of them have pleaded not guilty to Federal corruption charges.

Nassau County Executive Edward Mangano and his wife Linda were charged Oct. 20 in a 13-count indictment that includes charges of bribery, extortion, fraud and obstruction.

Also named in the indictment was Oyster Bay town supervisor John Venditto. The three were arraigned on the charges and each released on $500,000 bond.

Edward Mangano and Venditto, both Republicans, are charged with conspiring to receive bribes and kickbacks from a businessman in exchange for helping him obtain $20 million in loan guarantees.

Linda Mangano is charged with accepting a $450,000 no-show job at the businessman’s restaurant, and lying to Federal investigators.

The couple also face charges they accepted vacations and expensive gifts from the businessman.

The indictment says Venditto under pressure from Edward Mangano, worked to amend the town concession agreements. Under the arrangement, the town would repay the lender the entire amount if the businessman defaulted.

The indictment also says the businessman got “lucrative” government contracts, and paid Linda Mangano more than $450,000 for doing “little or no work.”

The Manganos’ attorney did not immediately respond to a request for comment. Venditto’s attorney declined to comment.
