ADA, Okla. (AP) — Oklahoma Attorney General Mike Hunter wants a national advocacy group to stop sending letters to the state demanding removal of religious articles from a state university's chapel.

Hunter wrote a letter Wednesday to the Washington, D.C.-based Americans United for Separation of Church and State saying the state can't find common ground with it and that further communication "is a waste of time and money."

Hunter's letter follows an Aug. 16 letter from the group demanding removal of religious articles from the Kathryn Boswell Memorial Chapel at East Central University in Ada. Hunter says the state rejects the group's demand that a cross and other articles be removed.

An attorney for the group, Ian Smith, accused Hunter of "political grandstanding" and says in an email the group is considering legal action.
