I've been wondering the same thing about...

The White House turned over last week 250 pages of emails from Vice President Dick Cheney’s office. Senior aides had sent the emails in the spring of 2003 related to the leak of covert CIA operative Valerie Plame Wilson, Special Prosecutor Patrick Fitzgerald revealed during a federal court hearing Friday.

The emails are said to be explosive, and may prove that Cheney played an active role in the effort to discredit Plame Wilson’s husband, former Ambassador Joseph Wilson, a vocal critic of the Bush administration’s prewar Iraq intelligence, sources close to the investigation said.

Sources close to the probe said the White House “discovered” the emails two weeks ago and turned them over to Fitzgerald last week. The sources added that the emails could prove that Cheney lied to FBI investigators when he was interviewed about the leak in early 2004. Cheney said that he was unaware of any effort to discredit Wilson or unmask his wife’s undercover status to reporters.
Cheney was not under oath when he was interviewed. He told investigators how the White House came to rely on Niger documents that purportedly showed that Iraq had tried to purchase uranium from the African country.

Cheney said he had received an intelligence briefing on the allegations in either December 2001 or January 2002.

Cheney said he was unaware that Ambassador Wilson was chosen to travel to Niger to look into the uranium claims, and that he never saw a report Wilson had given a CIA analyst upon his return which stated that the Niger claims were untrue. He said the CIA never told him about Wilson's trip.

However, the emails say otherwise, and will show that the vice president spearheaded an effort in March 2003 to attack Wilson’s credibility and used the CIA to dig up information on the former ambassador that could be used against him, sources said.

Some of the emails that were turned over to Fitzgerald contained references to Plame Wilson's identity and CIA status, and developments related to the inability of ground forces to find weapons of mass destruction in Iraq after the start of the war in March 2003.

According to sources, the emails also contained suggestions by senior officials in Cheney’s office, and at the National Security Council, on how the White House should respond to what it believed were increasingly destructive comments Wilson had been making about the administration's pre-war Iraq intelligence.
