Gov. Kathy Hochul traded barbs with top lawmakers Tuesday – calling one a liar – as pols canceled a closed-door meeting, signaling that a stalemate over the state budget will enter its third week.

A ticked-off Hochul told reporters Tuesday that Deputy Senate Majority Leader Michael Gianaris was wrong to deem her as the impediment to moving forward the $263 billion spending and policy package.

“I was responding to the criticism that this is trying to infer we are the roadblocks,” Hochul said at an unrelated event. “That was false, it’s been called out as false.”

The breakdown was evident when state Senate Democrats failed to hold a scheduled closed-door conference Tuesday, a source confirmed – a sign that Hochul’s talks with legislative leaders didn’t lead to a breakthrough compromise.

Gianaris, a powerful Queens Democrat who isn’t seeking reelection, said Monday that the governor refused to compromise on her proposal to change New York’s generous liability statutes in an effort to drive down car insurance.

“It’s a one-way street on the auto insurance issue,” an annoyed lame-duck Gianaris told reporters in the Senate lobby.

The governor, who’s running for re-election this year, is pitching her proposed revamp of car insurance laws as an affordability measure.

Hochul wants to change the definition of “serious injury” to make it harder to game the system with fraudulent lawsuits.

But the effort has run into opposition in Albany, with lawmakers such as Gianaris expressing skepticism that it’d actually result in lower insurance rates for New York motorists.

Hochul, for her part, has accused the powerful trial lawyers lobby of brazenly lying about her plan.

She doubled-down on the accusation Tuesday, tying Gianaris into her response.

“I was responding to criticism that was trying to infer that we are the roadblocks, that we’re not trying to cooperate, we’re not trying to move this process along. And that is not true,” she said.

“When I don’t hear the truth, I’ll always call it out, including the trial lawyers that he is defending who are lying about cases.”

The impasse over car insurance – and a separate disagreement about Hochul’s bid to delay the state’s controversial climate law’s mandates – prompted lawmakers to blow past the budget’s April 1 deadline.

Albany legislators have passed three stopgap measures extending government funding for a week each, with the latest expected to lapse Thursday.

Hochul has emphasized she’s compromised on some issues, but she’s not willing to budge on others like her car insurance proposal or hiking taxes.

“We have moved and we have listened to the legislators and their thoughts and, a few times evolved, but there are just some core values that I have and I’m not going to stop fighting to have an affordability agenda that the people of the state deserve to have,” she said Tuesday.
