(CNN) - Bob Dole is furious with Scott McClellan's public criticisms of the Bush administration, telling the former White House Press Secretary in an e-mail Thursday he is a "miserable creature" who is "spurred on by greed."
"There are miserable creatures like you in every administration who don’t have the guts to speak up or quit if there are disagreements with the boss or colleagues," Dole wrote in the personal e-mail. "No, your type soaks up the benefits of power, revels in the limelight for years, then quits, and spurred on by greed, cashes in with a scathing critique."
Dole spokesman Michael Marshall confirmed the authenticity of the e-mail, first reported by Politico and obtained by CNN.
Dole, the former Senate Majority Leader and 1996 Republican presidential nominee, also tells McClellan he is likely looking to "clean up" as "the liberal anti-Bush press will promote your belated concerns with wild enthusiasm."
"When the money starts rolling in you should donate it to a worthy cause, something like, 'Biting The Hand That Fed Me,'" he wrote. "Another thought is to weasel your way back into the White House if a Democrat is elected. That would provide a good set up for a second book deal in a few years."
Dole also made clear he has no plans to read the book.
"I have no intention of reading your 'exposé' because if all these awful things were happening, and perhaps some may have been, you should have spoken up publicly like a man, or quit your cushy, high profile job," he wrote. "That would have taken integrity and courage but then you would have had credibility and your complaints could have been aired objectively."
"You're a hot ticket now but don't you, deep down, feel like a total ingrate?"
