Around 700 migrant kids who were separated from their parents at the Mexican border are currently being housed in New York — more than twice as many as previously estimated, Gov. Andrew Cuomo said Thursday.

The governor says his administration only got the new figures by polling foster care agencies — because a federal gag order is preventing the organizations from telling the state how many kids are in their care.

“On a humanitarian level and a legal level, they have the legal obligation to tell me where they are,” he said on a conference call with reporters.

“They’re in my state. It’s my legal responsibility.”

Cuomo says he’s demanded the information in a letter and phone call to the federal Department of Health and Human Services — saying he has a duty to protect the children and provide them with services they’re currently being denied.

“It is a disgusting and absurd and inhumane position for HHS to say, ‘I’m not telling you where they are,’ to say, ‘I don’t want you to provide mental health services,’” he said.

The Department of Homeland Security said Tuesday that 2,342 children had been separated from their parents since early May, when the Trump administration’s “zero tolerance” policy of criminally prosecuting all adults who cross the border illegally began.

Cuomo said New York is getting a large number of the kids because it has one of the largest foster care networks in the country.

And more kids continued to pour in overnight, he said — despite President Trump signing an executive order Wednesday to keep border-crossing kids with their parents.

“It was a political pirouette,” he said of the order. “He wound up in the same position as when he started. The political pirouette was to confuse the press.”

The governor has pledged to file a lawsuit against the Trump administration over the family separations — and said he’s still pushing forward with the legal action.
