Anyone else hearing that FBI showed up to the McGraw-Hill building in Manhattan looking for Judith Regan? The Feds thought the controversial publishing impresario would be at the Sirius office, in the 6th Avenue skyscraper, for her Wednesday appearance on the satellite radio network, according to a tipster. But the show is pre-taped on Tuesday, so she wasn't there. The FBI agents told the Sirius receptionist they were sending a team to Regan's house as well. What on earth would they be looking for?

Regan claims to have an incriminating tape, which she is using as leverage in her lawsuit against News Corporation. Rupert Murdoch's media conglomerate fired the unpredictable publisher after she published a thinly-disguised confession by O.J. Simpson, accused of murdering his wife years ago. Regan also had an affair with Bernie Kerik, the corrupt aide to Rudy Giuliani who could sink his already holed campaign for the presidency. Who's on the embarrassing tape? In Manhattan book circles, word is none other than Jabba-like Roger Ailes, former Nixon aide and founder of Murdoch's Fox News.
