Fitzgerald is said by lawyers involved in the case and government officials to be examining possible discrepancies between documents he has gathered in the case and statements made by current or former White House officials during a three-month preliminary investigation conducted last fall by the FBI and the Justice Department. Some officials spoke to FBI agents with their lawyers present; others met informally with agents in their offices and even at bars near the White House.

...The suspicion that someone may have lied to investigators is based on contradictions between statements made by various witnesses in FBI interviews, the lawyers and officials said. The conflicts are said to be buttressed by documents, including memos, e-mail messages and phone records turned over by the White House.

At the same time, Fitzgerald is said to be investigating whether the disclosure of Plame's identity came after someone discovered her name among classified documents circulating at the upper echelons of the White House.

If Bush officials lied to the grand jury, it's more likely to be perjury. The perjury law is here. But the Government wouldn't charge perjury without two witnesses to prove it, as I explain here.

Update: I've moved all of TalkLeft's Valerie Plame posts (almost 100 I think) to a separate Valerie Plame category. If you want the first sentence or two to show up, just put Plame in the search box, or click here.
