In June of last year, Americans United for Separation of Church and State (AU) requested that the Internal Revenue Service (IRS) investigate Bill Keller for possibly violating the political campaign intervention prohibition for tax exempt organizations. Keller has a call-in show on a Tampa television station and a Web site called Liveprayer.com. On May 11, 2007 Keller warned listeners; "if you vote for Mitt Romney, you are voting for Satan!" Now, the public is aware that the IRS is in fact investigating the case. According to the St. Petersburg Times, "the IRS gave him a week to assemble documents and videos of his television programs. . . Keller said he is prepared to fight if his ministry loses its tax-exempt status."
