Cardinal Timothy Dolan blasted the Trump administration's policy of separating families at the U.S. border in an interview Friday.

Dolan called the practice "un-American and unbiblical."

It comes after Attorney General Jeff Sessions referenced scripture to claim the administration had the moral authority to forcibly take kids from their parents if they cross the border illegally.

Dolan told CNN anchor Chris Cuomo he thinks the attorney general might need a Sunday School refresher.

"If they want to take a baby from the arms of his mother and separate the two, that’s wrong," Dolan said. "I don’t care where you’re at, what time and what condition, that just goes against, you don’t have to read the Bible for that. That goes against human decency. That goes against human dignity. That goes against what’s most sacred in the human person."

Numbers from the Department of Homeland Security show nearly 2,000 minors have been separated from their families at the U.S. border over the six-week period between April 19 and May 31.
