Ohio Gov. Mike DeWine (R) signed a bill Wednesday that requires transgender students from kindergarten through college to use a bathroom that corresponds to their sex assigned at birth, although it has no enforcement mechanism.

The new law will require K-12 and college students to use bathrooms and locker rooms that match their sex assigned at birth.

The state is one of at least a dozen states to set restrictions on bathrooms for transgender students at public schools.

Republican Ohio Gov. Mike DeWine has signed a bill into law that will prevent schools from allowing students of the opposite sex into restrooms and locker rooms.
