None, as far as I know, but we should ask more of our leaders than that they just be non-criminals. The administration's current spin on the Rove situation reminds me of a fictitious political campaign from when I was a kid. I think the candidate was Alfred E. Newman of Mad magazine fame. His campaign slogan was something like, "Alfred E. Newman, Not Insane."

I don't think the relevant question is whether Rove is a criminal. The question is whether he has the country's interests at heart. The Plame matter, no matter how it turns out, tends to argue against Rove on that score, IMHO.
