The transgender bathroom battle is about to take another dramatic turn.

Texas and 10 other states are suing the Obama administration over a new directive allowing transgender students to use bathrooms and locker rooms in public schools that correspwith their gender identity.

The lawsuit, announced Wednesday in Austin by Texas Attorney General Kenneth Paxton, also includes Oklahoma, Alabama, Wisconsin, West Virginia, Tennessee, Maine, Arizona, Louisiana, Utah and Georgia. It accuses President Obama’s administration of “running roughshod over commonsense policies” that protect children, and asks a judge to declare the directive unlawful.

Conservative states had vowed defiance since the Justice Department handed down the guidance earlier this month. At the time, U.S. Attorney General Loretta Lynch said “there is no room in our schools for discrimination.”

The Department of Education ordered schools to create policies to grant bathroom access to transgender students in accordance with their identities or risk losing billions in federal funding. According to The Associated Press, Lt. Gov. Dan Patrickhas previously said Texas is willing to forfeit $10 billion in federal education dollars rather than comply.
