The Oklahoman reports that an anti-abortion group has sued Oklahoma State University, contending university officials refused to allow its members to distribute leaflets on the Stillwater campus. Cowboys for Life, a Oklahoma State student organization, argues that university officials singled out the group because it opposes abortion rights. The group seeks to have the university's facilities use policy declared invalid. Cowboys for Life had sought to hand out leaflets and carry signs at three locations on campus. The lawsuit asserts that Kent Sampson, the university's director of campus life, refused to allow the group to display graphic images in heavily trafficked areas of campus.
