"Physics professor Steven Jones has made numerous statements about the collapse of the World Trade Center. BYU has repeatedly said that it does not endorse assertions made by individual faculty. We are, however, concerned about the increasingly speculative and accusatory nature of these statements by Dr. Jones. Furthermore, BYU remains concerned that Dr. Jones' work on this topic has not been published in appropriate scientific venues. Owing to these issues, as well as others, the university has placed Dr. Jones on leave while we continue to review these matters."
