A Washington-based organization is threatening to sue metro Atlanta school boards for using church facilities to host their graduation ceremonies, but one conservative group maintains the schools are not in violation of the Constitution.

In response to the threatening letters Americans United for Separation of Church and State has sent to Atlanta-area school boards, Mat Staver of Liberty Counsel decides the organization is misrepresenting the Constitution. He points out that schools do have the right to choose graduation venues, even if they include religious facilities.
