Now reports are saying that 4 years of Rove email may be missing:

A lawyer for the Republican National Committee told congressional staff members yesterday that the RNC is missing at least four years’ worth of e-mail from White House senior adviser Karl Rove that is being sought as part of investigations into the Bush administration, according to the chairman of the House Oversight and Government Reform Committee.

GOP officials took issue with Rep. Henry Waxman’s account of the briefing and said they still hope to find the e-mail as they conduct forensic work on their computer equipment. But they acknowledged that they took action to prevent Rove — and Rove alone among the two dozen or so White House officials with RNC accounts — from deleting his e-mails from the RNC server. Waxman (D-Calif.) said he was told the RNC made that move in 2005.

In a letter to Attorney General Alberto R. Gonzales, Waxman said the RNC lawyer, Rob Kelner, also raised the possibility that Rove had personally deleted the missing e-mails, all dating back to before 2005. GOP officials said Kelner was merely speaking hypothetically about why e-mail might be missing for any staffer and not referring to Rove in particular.

That is an awful lot, but the White House feels that they don’t even have to turn over emails on RNC accounts, as Think Progress notes:

White House Counsel Fred Fielding, in a letter today, told Rep. John Conyers (D-Mich.) and Sen. Patrick Leahy (D-Vt.), chairmen of the House and Senate Judiciary committees, that the White House has not budged in its refusal to allow the panels to question several White House aides, including Karl Rove, about what they know regarding the firing of eight U.S. Attorneys, moving the two sides closer to a constitutional battle over the scandal.

Fielding also appears to be trying to head off an attempt by Conyers to obtain e-mails and documents from the Republican National Committee regarding the firings. … Fielding also said that “it was and remains our intention to collect e-mails and documents from those [RNC-controlled] accounts as well as the official White House e-mail and document retention systems” as part of a broader deal with the two committees on staffer testimony.

Color me stupid, but I believe they threw any chance of executive privilege out the door when they decided to break the law and use outside email addresses. I don’t think even the Republican leaning Supreme Court will side with Bush now.
