Gov. Lamont Rejects Kosta Diamantis' Corruption Allegations as 'Baseless and Absurd'

Connecticut Gov. Ned Lamont and his office are publicly rejecting corruption allegations made by former state official Konstantinos "Kosta" Diamantis, who fled to Greece before he was scheduled to be sentenced in a federal corruption case.

The allegations were contained in a 10-page email Diamantis sent to his attorney, Norm Pattis. CT Insider reported that it obtained the email and published selected excerpts. The full email, however, has not been made publicly available.

Lamont spokesperson Cathryn Vaulman called the allegations "baseless and frankly absurd," according to CT Insider. Lamont also dismissed Diamantis's claims, telling reporters that Diamantis was "making up a lot of junk."

According to CT Insider's report, Diamantis accused Lamont and members of his administration of using the legal and political system against him. He claimed that he was targeted to divert public attention from questions involving the governor, First Lady Annie Lamont and business relationships connected to state government.

Among the issues Diamantis raised were pandemic-era COVID-19 testing contracts involving Sema4, a company connected to investments by Oak HC/FT, the venture-capital firm co-founded by Annie Lamont.

Annie Lamont previously said that neither she nor the governor participated in the state's decision to contract with Sema4, that she recused herself from investment decisions involving the company and that any profits from those investments would be donated to charity.

Diamantis also continued to deny that payments he accepted from contractors were bribes. He claimed they were legitimate consulting payments and argued that his prosecution and trial were unfair.

At this time, the accusations contained in the email have not been independently substantiated. They are claims made by Diamantis after a federal jury convicted him.

Lamont's office said the accusations were an attempt to distract from Diamantis's own conduct and conviction. The governor emphasized that a jury found Diamantis guilty and said the state intends to hold him accountable.

The public response is significant because it confirms that the governor's office is aware of the email and is directly disputing the allegations. It does not, however, make Diamantis's claims proven facts.

Diamantis's accusations have not been proven.

A federal jury convicted Diamantis in October 2025 on 21 counts connected to a school-construction corruption scheme, including bribery, extortion, conspiracy and making false statements to federal investigators.

Diamantis was scheduled to be sentenced in federal court in Bridgeport on September 17, 2026. Instead, his attorney informed the court that Diamantis had traveled to Greece and would not appear. Authorities believe he used a Greek passport after previously surrendering his United States passport.

The U.S. Marshals Service subsequently began efforts to locate him. His sentencing was rescheduled for September 30, and he could potentially be sentenced even if he remains outside the United States.

Diamantis maintains that he is innocent and has reportedly sought a presidential pardon.

The existence of the email and Lamont's response are now matters of public record through published news reports. But important questions remain:

Will the complete 10-page email be released publicly? Does Diamantis provide documents or other evidence supporting any of his accusations? Will state or federal officials review any specific and verifiable claims contained in the email? Will Diamantis return to Connecticut or be brought back to face sentencing?

The New England Voice is seeking access to the complete email and will review any supporting documentation that becomes available. This report will be updated if the original document is released or if the governor's office, Diamantis's attorney or federal authorities provide additional information.
