NEW YORK — With an eye on a possible run for governor, Mayor Bill de Blasio on Thursday proposed offering year-round public school programming to students across New York state. 

In a video posted to his political website, the term-limited outgoing mayor pitched a plan to offer free universal 3-K and pre-K, as well as after-school and summer programming, to children statewide.

New York City earlier this year rolled out its own free summer program for students, dubbed "Summer Rising." De Blasio also instituted universal pre-K in New York City during his first term, following through on a promise he made during his first mayoral campaign.

Speaking about the statewide plan during an appearance on MSNBC's Morning Joe, de Blasio described it as "school for our kids, all day, all year, all for free."

"Imagine this: that we can provide, in this state, education for kids that goes until the end of the afternoon, that goes all year round for kids and families that want it, that is free for all," he said.

Asked by host Joe Scarborough whether he was promoting the plan as part of a run for governor of New York, however, de Blasio demurred.

"Well, I'm going to be in public service no matter what, Joe. You know that. But what I'm talking about right now is actually a vision, a vision of change," he said.

"You're presenting a position, a plan, a policy agenda for the state of New York. You can't implement that unless you're elected governor of New York. When do you make the announcement about that campaign?" Scarborough pressed on.

"Well, Joe, in the weeks ahead, I'll certainly have more to say about that," de Blasio responded.

While de Blasio earlier this month filed paperwork for a possible gubernatorial run, he has yet to officially enter a primary field that already includes incumbent Gov. Kathy Hochul, New York State Attorney General Letitia James and New York City Public Advocate Jumaane Williams.

De Blasio on Thursday said his statewide proposal, which his team says would cost about $5.4 billion, would be funded by increasing taxes for the state's wealthiest residents. He had aimed to fund his pre-K for all plan for New York City with a tax on the wealthy, but it was ultimately funded by state money.

"I'm very proud of this plan," he said at his morning briefing. "The bottom line here is that we're talking about a very different vision for education in the state."

On the heels of the announcement, it became clear the mayor was floating another idea from his 2013 mayoral run: getting rid of the horse carriages in Central Park. 

First reported by The New York Times, the mayor's team is exploring one final attempt to do away with the industry through legislation at the city council. 

A Council spokesperson told NY1 it has not received any proposal from the other side of City Hall.
