Minogue raised the issue in a Facebook post Saturday, asking whether Healey had made a deal with the union in exchange for its support. He pointed to a supplemental budget Healey filed in September that includes funding for finalized collective bargaining agreements. In a later statement, he called on Healey to say, under penalty of perjury, whether anyone in her administration or campaign discussed a connection between the contract and the endorsement.

The State Police Association of Massachusetts (SPAM) endorsed Healey on Sept. 10, along with three other law enforcement organizations. The union’s president, Brendan Murphy, said Sunday that Minogue’s allegation was “categorically false” and accused him of making an unsupported attack on troopers’ integrity.

Murphy said the agreement provides raises totaling 11% over three years, consistent with contracts for other state unions. He disputed Minogue’s claim that the raises amount to 18%.

Healey filed the supplemental budget on Sept. 23 to close the books on fiscal year 2026. It includes language covering economic benefits authorized by finalized agreements with SPAM and the Massachusetts Correction Officers Federated Union, and sets aside $30 million to cover costs. The bill does not specify the terms of the agreements.

The Massachusetts House passed its version of the supplemental budget last week, including the contract language and reserve funding. The Senate is not expected to take up the measure until after the election.

Minogue first raised concerns about union endorsements and contract negotiations during an Oct. 15 debate with Healey. In a campaign statement Monday, he said the timing of the endorsement and the conclusion of contract talks weeks before the election raised questions about transparency and the appearance of political influence. He said troopers deserved fair compensation and that his criticism was directed at Healey, not the officers.

At a campaign stop in Framingham on Monday, Healey said the endorsements reflected her work with law enforcement during her career as attorney general and governor. Asked directly whether a deal had been made, she called the allegation “lies and nonsense.”

Healey’s campaign spokesperson, Kerry Patrick Lyons, dismissed Minogue’s demand for a sworn statement as “an unhinged rant from an unhinged, desperate candidate.”

Murphy said the union’s endorsement reflected Healey’s record and the firsthand experience of its leadership. He urged Minogue to correct his claim and apologize to state police members.
