Ed Mangano was convicted in 2019 of accepting bribes and kickbacks in exchange for backing $20 million in indirect loan guarantees to Oyster Bay.
Former Oyster Bay Supervisor John Venditto surrendered Thureday morning to face new corruption charges in Nassau County.
Authorities said the ill-gotten gains included hotel and travel expenses; limousine services; a massage chair; an expensive watch; and hardwood flooring at the Manganos' home.
