Ten states have filed a lawsuit challenging a directive by the Obama administration advising schools to allow transgender students to use the bathroom of their choice.

The lawsuit, filed Friday, is led by Nebraska. Other states participating in the lawsuit include Ohio, Michigan, Arkansas, Kansas, Montana, North Dakota, South Carolina, South Dakota and Wyoming.

The lawsuit claims that the federal government does not have the authority to redefine the term “sex” to include gender identity.

Nebraska Attorney General Doug Peterson said Friday that the Department of Education had “taken action beyond the scope of their authority.”

A similar challenge announced in May is being led by Texas.

Nebraska Governor Pete Ricketts, a Republican, has urged school boards to reject the federal government's guidance, calling it “bullying.”

“I said this to local school boards as well, I urge you to not be bullied by this federal administration,” Ricketts said. “As a parent, I would be very concerned if someone of the opposite gender was trying to use the bathroom as my child.”
