Gov. Jared Polis of Colorado on Wednesday fired two members of his clemency board after they spoke out against his decision to commute the prison sentence of the election denier Tina Peters.

The board members, Hannah Seigel Proff and Azra Taslimi, had objected to Mr. Polis’s decision in May to release Ms. Peters from prison after pressure from President Trump.

After the commutation, Ms. Proff and Ms. Taslimi revealed that the board — appointed by Mr. Polis — had twice voted unanimously to reject Ms. Peters’s application for a shortened sentence. Mr. Polis, a Democrat, has the final decision, and overruled the board.

The board normally operates in secret, and does not disclose the pardon and commutation recommendations it makes to the governor. Ms. Proff and Ms. Taslimi said they had been compelled to pierce that veil of secrecy in Ms. Peters’s case.

On Wednesday, they said they had paid the price. They received a letter from the governor saying they were being dismissed for violating the board’s confidentiality standards.

“You breached the required duty of confidentiality by publicly divulging board members’ votes,” Mr. Polis wrote to each of the women, who shared the letters with The New York Times.
