Konstantinos Kosta Diamantis, a former Connecticut state lawmaker and deputy budget director, was convicted on October 22, 2025, of 21 federal counts including bribery, extortion, conspiracy, and lying to investigators. The charges stemmed from his use of his position overseeing state school construction grants to extort contractors for cash and secure employment for his daughter.
Separately, Diamantis faces pending federal charges for allegedly conspiring with former lawmaker Chris Ziogas to pressure state officials to cancel a 2020 Medicaid audit of an eye doctor’s practice. He has pleaded not guilty to these charges.
