President Biden won’t cough up major federal assistance to help New York City address the migrant crisis until after the 2024 presidential election, a prominent lawyer with close ties to Mayor Eric Adams’ camp claimed Wednesday.

Criminal defense attorney Arthur Aidala, appearing on the 770 WABC’s “Sid & Friends in the Morning” radio show, said a City Hall official relayed to him that the White House told Adams to suck it up until Biden is re-elected.

“I don’t think I’m betraying any confidences… They were on their hands and knees behind closed doors begging,” said Aidala, who is particularly close to Adams’ confidante and former chief of staff Frank Carone.

“And basically the word they got back was, `Hang on for a year. If Biden gets re-elected, he will cut you a check for a lot of money. But we’re not doing it until after the presidential election,,'” said Aidala.

“They’re going to Albany asking for help. They’re going to DC asking for help. They get bupkus.”

Adams on Wednesday said the city’s costs to aid the migrants could swell to $12 billion over three years 

The city has opened 194 sites, including 13 humanitarian relief centers — which are operated by the public hospital system — to accommodate the asylum-seekers.

Nearly 100,000 migrants, including 57,300 currently in the shelter system, have been processed in the Big Apple.

Gov. Kathy Hochul and the state Legislature this year delivered $1 billion in emergency assistance to the city to shelter migrants.

The governor also offered the use of state facilities as encampments to house migrants — including Creedmoor Psychiatric Center.

But Hochul has also been accused of having a slow-footed response to the crisis, which she disputes.

The governor said this week the state will likely kick in another $1 billion in funds next year to handle the unrelenting flow of migrants coming from the Mexican border.

The feds have kicked in a modest $104.6 million.

Meanwhile, Aidala said a high ranking City Hall official told him the city is struggling to even find enough contractors to run the growing number of emergency migrant facilities.

“I was with a very high ranking official yesterday from City Hall, who spoke genuinely to me and said, `We’re at wit’s end. The issue is not just finding places for these people. But when we find places for people we can’t find anyone to run the thing,'” Aidala said.

He said he was told the migrant crisis “has almost broken the [Adams] administration because it is part of every conversation of everything they’re doing.”

The mayor and White House had no immediate comment.
