Executive Privilege on RNC Emails?

White House Raises Potential Executive-Privilege Claim on RNC E-mails

"In a letter to Robert Kelner, the RNC's counsel, Emmet Flood, a special counsel to President Bush, reiterated the desire of the White House to review any materials it is considering turning over the House Judiciary Committee before doing so."

A little more on it here, Rep. John Conyers (D-MI) isn't buying it: "The White House's position to clear all RNC emails before they can respond to our request is extreme and unnecessary. This is a clear attempt, on the Administration's part, to delay this process and keep the wheels of Justice turning slowly."
