President Trump says the amount of money the government spent on Puerto Rico after Hurricane Maria is “beyond belief” and “has to be studied.”

“You know we’re trying to save money, you know I’m cutting budgets and we’ve cut a lot of budgets,” the president told The Post in an Oval Office sitdown Wednesday when asked about the hefty price tag for upgrading the Hudson River rail tunnels.

“But you know we had a thing called hurricanes and fires that happened that had a huge impact on the numbers,” he continued.

“On the money that’s being spent, and a place where money is being spent more than anywhere else? Puerto Rico. Puerto Rico. The money we have spent on Puerto Rico is beyond belief.”

Despite those efforts, Trump said, his administration gets no gratitude from officials of the US commonwealth.

“We got no credit for it, but the money that they want, it’s a tremendous amount of money. It’s beyond anything that I’ve ever seen, far more than Florida, far more than Texas, and it has to be studied. It has to be studied, it’s a massive amount of money. And the problem is no matter how good a job you do, you don’t get credit for it,” he said.

Puerto Rico, in a report to Congress, estimated the total cost of recovery from Hurricane Maria at $139 billion. FEMA has so far authorized $60 billion in disaster relief funds.

“You have, you have a mayor of San Juan, Puerto Rico, who’s totally incompetent. And you know, no matter what you do, she was complaining two weeks before the hurricane got there,” he said about Carmen Yulín Cruz Soto, who has repeatedly criticized Trump for what she called a slipshod response to the disaster.

“She was complaining about the hurricane before it was formed. There was no sense of appreciation, and the money is massive. It’s beyond massive. And so I’m studying that very seriously,” the commander-in-chief stated, without elaborating on what kind of “study” would be conducted.

The president acknowledged that the existing Amtrak tunnel beneath the Hudson River was old and in bad shape and needed upgrading, claiming it’s “probably the world’s most expensive project.”

He said he had seen a video showing the tunnel’s deteriorating condition that Gov. Andrew Cuomo sent him before the pair had a lunch meeting on the topic Wednesday.

“Well, we’re looking at it now, the tunnel is very old, and what he did was he sent me video talking about the existing tunnel, and it is a very old tunnel, and we’re gonna talk about it, I’ve already spoken with Senator Schumer about it, and others, and for New York it’s a very big deal. And they’re seeing me, and we’re gonna look at it, it’s a very expensive project as you know,” he said.

The Obama administration had said it would fund half of the project’s cost, but Trump and Transportation Secretary Elaine Chao killed the funding, with Chao saying that New York and New Jersey were rich states that should pay more for it themselves.

Cuomo proposed seeking bids from private companies as part of a plan to redraw the project that he gave Trump.

Cuomo described his meeting with Trump as positive and said afterward during a press conference in Manhattan that Trump was receptive to his proposal to get a cost estimate for tunnel construction that both he and the president would trust.

The governor said he proposed rethinking the overall $30 billion project, which includes a comprehensive overhaul with new tracks, new train station construction and other improvements, to focus on the $13 billion rail tunnels first.

He said he would restructure the Gateway Program Development Corp., which currently oversees planning, to remove Amtrak and replace it with a different federal government representative that would work alongside New York and New Jersey.

“I’m not going to sign a check until I know what the amount of the check is,” Cuomo said. “I’m not going to do it on an Amtrak estimate.”
