We're sure Congress will still be seeking Karl RoveKarl Christian RoveKarl Rove: 'Long way to go' for Sanders to capture nomination: 'The field is splintered' Karl Rove argues Clinton's impeachment was 'dignified' Washington Post fact-checker gives Plame three Pinocchios for Libby claim MORE's testimony. The White House will probably take the same line as they have with Harriet Miers, which is that executive privilege prevents him from testifying, and they're not going to waive it. They'll do everything they can to keep him from testifying. He's the one they want to testify least, because he knows where all the bodies are buried.

That said, he should offer his testimony to Congress. In an open society, the public deserves to know the truth about what the government is up to. Just because they can claim executive privilege doesn't mean they have to.

In any event, this claim of executive privilege regarding Rove and Harriet Miers could still lead to a constitutional showdown in the courts. We don't think Congress will just accept a claim of executive privilege.
