A judge temporarily ordered the Tennessee Department of Health not to give immigration authorities information about roughly 400 seriously sick and disabled immigrant children who are enrolled in a healthcare assistance program.

The restraining order was issued Wednesday at the request of three Nashville doctors who treat some of those children and who sued after state officials sent letters to providers and immigrant families saying a new law required them to share identifying information for those on the program after the end of June.

The law was part of a group of bills that Tennessee Republicans introduced this year to support President Donald Trump’s immigration crackdown.
