Konstantinos 'Kosta' Diamantis

Konstantinos Kosta Diamantis, a former Connecticut state representative and former deputy budget director, was convicted on October 22, 2025, of 21 federal counts, including bribery, extortion, conspiracy, and making false statements to investigators. Prosecutors proved that from 2018 to 2021, he abused his position as director of the Office of School Construction Grants and Review to solicit bribes from contractors in exchange for lucrative state-funded projects. Evidence revealed Diamantis threatened to terminate contracts if he was not paid and pressured a firm to hire his daughter at an inflated salary. He admitted to receiving payments but claimed they were for legitimate consulting. Sentencing is set for January 14, 2026, with legal counsel noting he faces a potential sentence of 10 to 12 years. Diamantis also faces a pending separate federal case, where he pleaded not guilty to charges of bribery and extortion related to allegedly pressuring state officials to cancel a 2020 Medicaid audit for an eye doctor. He is currently free on bond.
