"I don't know anything about it. And, it sounds to me like a kind of gossip column story more than a real story."

Rudy Giuliani brushes off a question about Judith Regan's $100 million lawsuit against HarperCollins. Can anyone understand the lawsuit?

Regan... says that "it is now widely accepted" that one of Giuliani's vulnerabilities is the 52-year-old Kerik. Because of Regan's affair with Kerik, court papers say, a senior executive at News Corp., HarperCollins' parent company, told her he believed she had information about Kerik that could hurt Giuliani's campaign and she should lie to federal investigators.

She also contends another executive told her to withhold documents that were relevant to the government's investigation of Kerik, and court papers say that HarperCollins and News Corp. "knew they would be protecting Giuliani if they could preemptively discredit her."

I mean, can anyone understand this lawsuit other than as a way to get publicity for an attack on Giuliani? What's the legal claim?

ADDED: Here's the PDF of the complaint. The claims are mostly for defamation, for what executives at HarperCollins said about her when she was fired, plus claims for breach of contract, breach of the duty of fair dealing, sex discrimination, retaliation. Most of the controversy seems unrelated to Kerik and Giuliani. Here's how the Smoking Gun sums it up:

Judith Regan, the volcanic publishing industry figure who sought to publish O.J. Simpson's "I Did It" (and trysted with Bernard Kerik in an apartment overlooking Ground Zero) today sued Rupert Murdoch's media conglomerate for defamation, claiming that she was unjustly tarred as an anti-Semite when fired last year.... According to Regan, Murdoch employees were aware of her personal relationship with Kerik and, fearing she had damaging information on Giuliani's former police commissioner and business partner, "knew they would be protecting Giuliani if they could preemptively discredit her." The Murdoch firms did this, Regan charges, by claiming she made anti-Semitic statements during a phone conversation with a HarperCollins lawyer.
