Some children who were separated from their parents at the United States-Mexico border are being held in New York and the Hudson Valley.

Gov. Andrew Cuomo said at least 70 children who were separated from their parents are currently being housed in New York facilities that have contracts with the federal government, including in Yonkers, Dobbs Ferry, Irvington, Somers and the Bronx.

This follows President Donald Trump's zero-tolerance program that allows children to be separated from their parents at the U.S.-Mexico border.

The governor says he's tried sending the children aid, as well as mental and social services, only for them to be turned away. All of the contracted private facilities, he says, have been gagged by the federal government.

Cuomo will be filing a lawsuit against the federal government saying that the separation of children and their parents is unconstitutional.

The Westchester County executive said the president needs to stop on this issue.

"He needs to stop on this one. He needs to realize that he has lost a wide swatch of the American people," said County Executive George Latimer. "Not that we all need to agree on the same immigration policy, but this is a matter of humanity."

House Republicans are still working on immigration bills.

President Donald Trump signed an executive order Wednesday to keep families together at border. He says a 'zero-tolerance' prosecution policy will continue.
