Konstantinos 'Kosta' Diamantis

Konstantinos 'Kosta' Diamantis, a former Connecticut lawmaker and state official, has been publicly reported to face serious legal allegations involving corruption. In May 2024, he was arrested and charged with federal extortion, bribery, conspiracy, and false statement offenses. Specifically, Diamantis, who served as a top official in Connecticut's Office of School Construction Grants and Review, was accused of extorting private contractors by demanding and receiving thousands of dollars in bribes in exchange for overseeing state funds for school construction projects (NBC Connecticut). He appeared in federal court in Hartford, pleaded not guilty to 22 charges, and was released on a $500,000 bail (NBC Connecticut). There are no publicly reported allegations or cases of misconduct, fraud, or ethics violations beyond this incident. As of April 2026, Diamantis has not been convicted or formally sentenced on these charges, and he continues to deny any wrongdoing. This case appears to be ongoing, and no further details about case outcomes or additional controversies are available in the current public record (NBC Connecticut).
