Senate Minority Leader Chuck Schumer introduced a bill that aims to end the separation of migrant children from their families while improving living conditions in border detention facilities.

The bill, called the “Stop Cruelty to Migrant Children Act,” was unveiled on Capitol Hill Thursday morning.

“It is not American to treat children like this,” Schumer said, calling for “nasty and vicious” people in the Trump administration — namely immigration hardliner Stephen Miller — to stop using migrant children as political pawns.

Besides legislating the end of child separation, the bill will bump up health and safety protection for detained kids, including getting them swift medical assessments. It will also require that Congress receive monthly reports on the number of children in custody.

The measure has already amassed more than 20 Senate co-sponsors, all Democrats — including some running for president, according to a source close to the bill drafting — though it doesn’t yet have companion legislation in the House, where it would pass.

Without Republicans on board, it will go nowhere in the Senate.

It does, however, have Hollywood support, as actress Alyssa Milano gave it a plug on Twitter Wednesday, calling it “HUGE NEWS.”
