Each filed a separate lawsuit in Oklahoma City federal courtOKLAHOMA CITY — Oklahoma’s attorney general and state Department of Education are both suing the Biden administration over new Title IX rules protecting gender identity in schools.Attorney General Gentner Drummond and the state agency each announced Monday they filed lawsuits against the U.S. Department of Education in Oklahoma City federal court.
