Eleven states and state officials filed a lawsuit Wednesday challenging the Obama administration over federal guidance directing schools to allow transgender students to use restrooms and other facilities that match their gender identities.

The federal lawsuit, filed in the U.S. District Court for the Northern District of Texas, states that the guidance “has no basis in law” and could cause “seismic changes in the operations of the nation’s school districts.”

State officials have hinted they might file a legal challenge since the Obama administration released a letter earlier this month from the Justice Department and the Education Department that the federal agencies said was in response to questions from schools around the country.
