unaware of much of the Xenu story which is first revealed on Operating Thetan level three, or "OT III". Because the information imparted to members is to be kept secret from others who have not attained that level, the member must publicly deny its existence when asked. OT III recipients must sign an agreement promising never to reveal its contents before they are given the manila envelope containing the Xenu knowledge. Its knowledge is so dangerous, members are told, that anyone learning this material before they are ready could become afflicted with pneumonia. Religious Technology Center director Warren McShane testified in a 1995 court case that the Church of Scientology receives a significant amount of its revenue from fixed donations paid by Scientologists to study the OT materials. McShane said that Hubbard's work "may seem weird" to those that have not yet completed the prior levels of coursework in Scientology. McShane said the story had never been secret, although maintaining there were nevertheless trade secrets contained in OT III. McShane discussed the details of the story at some length and specifically attributed the authorship of the story to Hubbard. When John Carmichael, the president of the Church of Scientology of New York, was asked about the Xenu story, he said, as reported in the September 9, 2007, edition of The Daily Telegraph: "That's not what we believe".

In a BBC Panorama programme that aired on May 14, 2007, senior Scientologist Tommy Davis interrupted when celebrity members were asked about Xenu, saying: "None of us know what you're talking about. It's loony. It's weird." In March 2009, Davis was interviewed by investigative journalist Nathan Baca for KESQ-TV and was again asked about the OT III texts. Davis told Baca "I'm familiar with the material", and called it "the confidential scriptures of the Church". In an interview on ABC News Nightline, October 23, 2009, Davis walked off the set when Martin Bashir asked him about Xenu. He told Bashir, "Martin, I am not going
