Oklahoma’s Republican attorney general has filed a lawsuit to stop what would be the nation’s first publicly funded religious school.

Attorney General Gentner Drummond filed the lawsuit Friday with the state Supreme Court against the Oklahoma Statewide Virtual Charter School Board.

The board voted 3-2 in June to approve the charter school application by the Catholic Archdiocese of Oklahoma.

The board’s actions came despite a warning from Drummond that they were violating both the state and U.S. constitutions.

A message left Friday with the board’s executive director wasn’t immediately returned
