Despite the recent rash of NYPD suicides, a mental health program pushed by Mayor Bill de Blasio’s wife, ThriveNYC, pulled out of a seminar for first responders — because a pro-cop group was co-sponsoring the event, The Post has learned.

The $1 billion signature program by first lady Chirlane McCray was on board to staff the upcoming “mental health first aid training” event but pulled its offer of psychological counselors once it learned Blue Lives Matter was involved, said Councilman Joe Borelli.

“This was going to be to train police officers how to recognize signs of depression,” said the Staten Island Republican.

“We had people in the police department who wanted to save lives and now it’s canceled and we have to reschedule it because of the PC environment that de Blasio has caused.”

Borelli said his office was approached in June by Blue Lives Matter about setting up mental health programs for cops, and at first Thrive jumped at the chance to take part.

That enthusiasm plummeted when Borelli’s office showed Thrive higher-ups the event flyer, which featured the program’s logo alongside that of Blue Lives Matter, said Borelli chief of staff Frank Mascia.

“When Sarah [Solon, Thrive’s deputy director] saw the flyer, she expressed on the phone, ‘Oh, I wasn’t aware of the logistics’ — which implied she saw Blue Lives Matter sponsorship,” said Mascia. “She explicitly asked me not to have the other groups on the flyer.”

Blue Lives Matter, formed in the aftermath of the fatal 2014 ambush of NYPD officers Rafael Ramos and Wenjian Liu, is regarded as a controversial group by some for its juxtaposition to Black Lives Matter.

After Mascia refused to make the change, Thrive pulled its support of the event, which had been scheduled for Aug. 19.

Without the well-funded Thrive’s counselors, Borelli and Blue Lives Matter were forced to postpone until September, as troubled cops’ lives remain in the balance.

“This program, it could have done a lot of good things,” said Blue Lives head Sgt. Joseph Imperatrice. “This is the problem: You reach your hand to try to do good things and, in this case, save lives, and because of political agenda they want to pull it back.

“Why you’d want to shut something like this down just doesn’t make sense.”

The pet project of McCray for much of her husband’s tenure, Thrive has been panned as a mismanaged money pit, producing next to no concrete results despite a bloated $250 million annual budget.

Asked about pulling the counselors from the Staten Island event, Solon would only say, “Thrive remains committed to working with … Borelli’s office to bring mental health first aid training to first responders. If he wants to organize a dedicated and private training, we are ready to be there.”

That explanation wasn’t good enough for NYPD insiders, who have seen nine of their fellow Finest end their lives so far in 2019, including one on Wednesday — and have to wonder daily whether number 10 might be someone they know.

“You want to pick and choose who gets to use your money for mental health?” asked one high-ranking police source. “The police department doesn’t get to choose who we save and who we don’t save.”
