Sources said on Wednesday that Tom Homan, the border czar, expressed dissatisfaction with the lack of support from New York City in implementing President Trump’s immigration policies. This could lead to a potentially difficult second meeting with Mayor Eric Adams.

Homan will make the newly Trump-indebted Adams come to him at New York City’s ICE headquarters at 26 Federal Plaza for the Thursday morning meeting, which will mark the pair’s second face-to-face, sources told The Post.

The mayor discussed reopening ICE’s office on Rikers Island during the pair’s first sit-down in Gracie Mansion in December, and he left it vowing to crack down on criminal migrants.

Hizzoner also said at the time he was eyeing an executive order to “unravel” confusing sanctuary rules and policies for how New York City can work with federal immigration authorities.

But Adams has apparently not made enough effort to please Homan since the meeting, sources said.

“Homan is not happy and hasn’t seen enough progress,” a source with knowledge of the meeting said.

“Homan wants something immediate and doesn’t want to wait till next January. The mayor has emergency order power. He’s going to have to beg and be a good boy for Trump.”

Homan revealed he’d be meeting again with Adams during a Tuesday radio interview, saying he wants the mayor to direct the NYPD to tip off the feds about the whereabouts of criminal migrants.

“I’m hoping we come to an agreement where his officers will help my officers remove these public safety threats, especially Tren de Aragua and the other alien gangs that are creating havoc in New York,” Homan said. 

The border czar didn’t return requests for comment from The Post Wednesday.

Mayoral spokeswoman Kayla Mamelak said Adams has long been clear he wants to work with Trump’s new administration, “not war with them.”

“That work includes meeting with ‘Border Czar’ Tom Homan to discuss going after the violent offenders who are wreaking havoc on our streets,” she said in a statement.

“We will continue to explore all lawful processes to remove violent migrants from our city. We hope to increase collaboration across law enforcement agencies to ensure we are working together to prevent violent gang activity.”
