Two of Gov. Kathy Hochul’s big proposals — a cellphone ban in schools and tax rebate checks for New Yorkers — may not survive state budget negotiations, which have now begun in earnest ahead of the April 1 deadline.

“What a radical concept, the thought that students should be paying attention to their teachers!” Hochul said on Tuesday in Albany, building off her successful crusade against social media targeting minors.

“I’ve been asked by many legislators, administrators, school superintendents and others to be the heavy. This is a tough, tough decision for them to go up against school boards and parents,” she added.

Smartphone use would be banned on school grounds for a full school day across New York, according to Hochul’s plan.

“I’m committed to fighting for bell to bell. This is what the experts say. This is what the parents want. This is what the teachers want,” she said.

There’s just one problem: she needs to convince the state Legislature.

“The question is, do you give the school districts flexibility to come up with their own or just one uniform policy across the state?” Democratic State Assembly Speaker Carl Heastie said during a separate press conference with reporters in the State Capitol Building.

“There are districts that have gone ahead and done different things that they feel are working, from superintendents who want a little bit of flexibility. So, we have injected that into the conversation as well. There is no doubt that we know that students will be better off if their phones are not with them and they’re able to concentrate on their lessons,” Democratic state Senate Majority Leader Andrea Stewart-Cousins said later.

Hochul is also facing a pushback from some lawmakers against her proposal to issue tax rebate checks. The plan slashes taxes for some middle-class New Yorkers and would redistribute $3 billion in sales tax revenue to taxpayers through checks ranging from $300 to $500.

“I cannot guarantee that the money will be there. I’m not in the habit of spending money we don’t have. This is one time,” she explained.

But state senators prefer a different strategy: they want to dole out money to seniors over a three-year period and expand tax credits to families and small businesses.  

“Rather than to provide a $300 check, we wanted to target it to seniors for three years. We managed working family tax credit for the same period, and we converge on small businesses by reducing their unemployment insurance tax employers,” Stewart-Cousins said.

The legislature is also pumping the brakes on changing what’s known as discovery deadlines for prosecutors to hand over evidence, involuntary commitment standards for the mentally ill — and forking over billions of dollars to cover future MTA projects.

“We’re seeing the consequences of not funding the capital plan for decades [to] come to roost right now with the way that the state of our system is in terms of more breakdowns, I’m seeing this happen on the R line right now the cars are breaking down more frequently. We need to invest!” state Sen. Andrew Gounardes, a Brooklyn Democrat, said.

Hochul and legislators are also worried about potential federal funding cuts from the Trump administration, but have yet to make any changes to their proposed financial plans.
