Former Aide Blames Bush for Leak Deceit

Isn't this grounds for impeachment?:

Former White House press secretary Scott McClellan blames President Bush and Vice President Dick Cheney for efforts to mislead the public about the role of White House aides in leaking the identity of a CIA operative.

In an excerpt from his forthcoming book, McClellan recounts the 2003 news conference in which he told reporters that aides Karl Rove and I. Lewis "Scooter" Libby were "not involved" in the leak involving operative Valerie Plame.

"There was one problem. It was not true," McClellan writes, according to a brief excerpt released Tuesday. "I had unknowingly passed along false information. And five of the highest-ranking officials in the administration were involved in my doing so: Rove, Libby, the vice president, the president's chief of staff and the president himself."
