A national organization focused on the separation of church and state has requested Auburn University to "abolish the chaplaincy" working inside the doors of its athletics department, calling the chaplain's presence unconstitutional.

The Freedom From Religion Foundation (FFRF) filed a letter to Auburn University president Jay Gogue Tuesday detailing its request. The letter includes concerns related to Rev. Chette Williams' presence within the football program, which the organization believes leads to the failure to "properly protect your student athletes' rights of conscience and pose(s) a high degree risk of discrimination" for those falling outside of certain religious groups.

"This public university grants him special privileges and unrestricted access because he is a Christian clergyman," according to a report released by the organization Wednesday.

Auburn University released a short statement Thursday.

"Chaplains are common in many public institutions, including the US Congress. The football team chaplain isn't an Auburn employee, and participation in activities he leads are voluntary."

The organization has sent similar letters over the last year to universities across the south, including Ole Miss, Mississippi State, Clemson, South Carolina and Georgia. Auburn's letter arrives nearly one year after the organization sent an open records request to the university, which has not been fulfilled. FFRF, via its Twitter account, said Auburn cashed a $500 deposit for the records, but a university official told AL.com Thursday the check has not been used. The tweet was deleted Thursday morning.
