School officials in a suburban Chicago district may back out of a deal with the U.S. Department of Education allowing a transgender student to use a girls' locker room.

Township High School District 211 Superintendent Daniel Cates on Friday angrily condemned a top federal official for how she portrayed his description of the settlement.

Cates says the department's Office of Civil Rights "acted in bad faith," so the district will convene an emergency board meeting to discuss actions, "including the potential retraction of the agreement."

Cates and the government are at odds over whether the settlement requires the student to use privacy curtains. The student was born male and identifies as female.

The district has been at risk of losing millions of dollars in federal funding over the issue.
