Gov. Andrew Cuomo chided Vice President Mike Pence over the Trump administration’s immigration policies as the VP raised funds in central New York on Tuesday for Rep. John Katko.

In a letter to Pence, Cuomo referenced the vice president’s own heritage and immigrant grandfather.

“Today this nation’s commitment to openness and tolerance is under siege by your administration,” Cuomo said. “Your policy of ripping children from their parents is a moral outrage and an assault on the values that built this state and this nation. This policy makes it very clear you have forgotten what made America great.”

Cuomo has blasted the Trump administration’s immigration policies over the last year and a half as the issue comes to a crisis level stemming from border enforcement agents separating families. The Trump administration has falsely blamed Democrats for the policy while insisting it is following a pre-existing law.

“If the parents’ anguish does not compel you to end this policy, then the children’s plight must,” Cuomo said. “I have heard the terrifying sobs of the children separated from their parents. And I know that your administration’s actions will have devastating long-term consequences for these children. Research and common-sense point to the developmental effects of depriving children of their parents. Such a traumatic experience can in fact trigger irreversible physical and psychological harm.”

At the same time, Cuomo continued to knock immigration enforcement efforts in New York, including the detention of an undocumented man in New York after delivering a pizza to a military base.

“I have already expressed my grave concerns with this administration’s anti-immigrant tactics, including when I requested the Department of Homeland Security Acting Inspector General to investigate their discriminatory tactics in our state and called on him to tell us what his office is doing about the assault on immigrant families along the border,” Cuomo said. “And I will continue to fight to defend our American values and protect the rights of all New Yorkers.”
