An Obama appointed judge has ruled that the Trump administration must provide mental health services to separated migrant families.

According to The Daily Caller:

A federal judge has ruled that the U.S. government must provide mental health services to the thousands of migrant parents and children who were separated at the southern border.

In a ruling late Tuesday, Judge John Kronstadt of the United States District Court in Los Angeles found the Trump administration responsible for the mental trauma caused by separating illegal alien families, according to a report from the New York Times. Kronstadt issued a preliminary injunction, ordering the administration to make available mental health services for those who experienced forced separation.

Psychological counseling and mental health screenings are among the services that must be provided by the Trump administration. These services — likely to be provided for a long period of time — are expected to be an expensive undertaking by the government, given the large number of illegal aliens who were subjected to separation.

“This is truly groundbreaking,” the dean of the University of California Berkeley School of Law, Erwin Chemerinsky, said to the Times about the ruling. “The court is recognizing that when a government creates a danger that inflicts trauma, the government is responsible for providing a solution. It is not something I have seen a court do before.”

The Trump administration will likely appeal the ruling as they continue to work to reform the immigration system.
