The head of the Environmental Protection Agency for two Republican presidents criticized President Bush's record on Monday, calling it a "polluter protection" policy.

Russell E. Train, who headed the EPA from September 1973 to January 1977 -- part of the Nixon and Ford administrations -- said Bush's record on the environment was so dismal that he would cast his vote for Democrat John Kerry.

"It's almost as if the motto of the administration in power today in Washington is not environmental protection, but polluter protection," Train said. "I find this deeply disturbing."

In 1988, Train was co-chairman of Conservationists for Bush, an organization that backed the candidacy of George W. Bush's father. (CNN)
