Gov. Ned Lamont has officially been served.

On Thursday afternoon, the governor received a subpoena to testify at his former budget deputy’s bribery and extortion trial.

It’s not clear if Lamont will actually take the stand, but jurors will hear from Kosta Diamantis as early as next Wednesday, his lawyer said.

Lamont’s office has retained an outside attorney to review the subpoena. Morgan Paul Rueckert, with Shipman and Goodwin, represented the state during the multi-year federal investigation into Diamantis.

“Gov. Lamont is not a party to this case and has no involvement in the underlying criminal allegations,” said Lamont communications director Rob Blanchard. “Attorney Rueckert is reviewing the subpoena and will discuss the matter with defense counsel and the Government. He will then respond as appropriate through the legal process on the issue of whether the testimony is relevant, necessary or meaningful to the case before the Court.”

Lamont insisted he was unaware of any wrongdoing until the FBI probe began in 2021.

“As soon as we got some wind that something may not be right, we changed the actors there," he said on Tuesday. "But I’ve got to do everything I can to make sure something like this can never happen again.”

Attorney General William Tong's office would not say if he will move to block Lamont’s testimony.

“We have accepted service on behalf of the Governor and will respond accordingly,” said spokesperson Elizabeth Benton.

Diamantis’ lawyer won’t decide whether to call Lamont as a witness until after his client testifies next week.

“I understand that Mr. Lamont has had lawyers from the AG’s office observing the trial,” defense attorney Norm Pattis told reporters. “They have not talked to me, so I don’t know.”

Diamantis oversaw hundreds of millions of dollars as head of Connecticut’s Office of School Construction Grants and Review.

But prosecutors say those lucrative contracts came with a price.

Diamantis demanded bribes from contractors – and then lied about it to the FBI – according to a 22-count federal indictment. His trial began Monday in Bridgeport.

On Thursday, three more witnesses said Diamantis pressured them to hire contractors that were either unqualified or not needed. Two contractors have already testified that they paid Diamantis more than $100,000 in bribes – once in a restaurant bathroom and another time on the side of the road.

“I felt like a drug dealer,” said Antonietta Roy, owner of Construction Advocacy Professionals (CAP).

CAP was paid $2.2 million to serve as a construction administrator for projects in Tolland and Hartford. Tolland’s school superintendent told jurors that Diamantis told him to “just get out of the way” and hire Roy.

“I didn’t feel like I had any practical choice,” Dr. Walter Willett testified. “There are people [on our staff] who felt like they could probably do that work.”

Melvyn Colon felt the same way.

Colon was head of the Hartford School Building Committee. He said the board hired Roy as a construction administrator – even though CAP was the second-highest bidder and the city already had a project manager – because “it was suggested to me by Mr. Kosta” during a school tour.

“He made decisions on what got funded and what didn’t get funded, so his opinion mattered,” Colon said.

Colon told jurors it was “unprecedented” for the state’s school construction chief to recommend a winner before bids even came in.

The final witness was Jack Butkus of ARCADIS, a firm that oversaw school construction for Hartford. He testified that Diamantis threatened to pull state funding if Acranom Masonry wasn't awarded a $3 million contract – despite concerns about sloppy work.

“We were between a rock and a hard place,” Butkus said. “The owner wasn’t getting what they were paying for.”

Diamantis is eager to tell his side of the story.

“You will probably hear my testimony – when the time comes,” he told reporters on Tuesday.

Pattis plans to call Diamantis as his first witness on Wednesday or Thursday. He could spend two days on the stand.

“Listen carefully to Mr. Diamantis' testimony,” Pattis said.

In court, Pattis suggested that the governor's office pressured him to keep school construction costs “on time and under budget.”

“I heard a description of a man who was a hands-on, aggressive manager on behalf of the state of Connecticut,” Pattis told reporters. “I think many taxpayers wish we had more.”

Pattis also suggested that Lamont personally approved paying 100% of CAP’s costs for a renovation in Hartford.

Former Hartford mayor Luke Bronin, who is now running for Congress, may also be called to the stand.

“So Luke, if you’re out there, give the U.S. Marshals a call,” Pattis joked.

Diamantis’ trial resumes next Tuesday following a long holiday weekend.

Federal prosecutors plan to call Acranom owner Sal Monarca and Hartford city engineer Frank Dellaripa, who Diamantis referred to as “my guy” in text messages to Monarca. Jurors will also hear from FBI agents who interviewed Diamantis and see his videotaped interviews.

The government expects to finish presenting its case by late Wednesday.
