With the Iowa caucuses 50 days away, more questions about Giuliani’s past have emerged in recent days that could threaten his candidacy. On Friday, his personal friend and business partner Bernard Kerik was indicted on 16 counts of federal corruption charges, including bribery and tax fraud. On Tuesday, it was revealed that one of Kerik’s former lovers, Judith Regan, had sued Rupert Murdoch’s News Corp and accused the company of pressuring her to commit perjury in order to protect Giuliani’s presidential ambition. We speak to investigative reporter and Village Voice senior editor Wayne Barrett, author of two books on Giuliani.
