In some of the strongest language yet coming from the Hollywood left, Peter Fonda called President Obama a “f—-ng traitor’} in an e-mail the actor said he sent to protest the Gulf oil spill and the response afterward.

Fonda was appearing at a press conference at the Cannes Film Festival to promote a documentary he co-produced, “The Big Fix,” about the spill and the cleanup.

“I sent an email to President Obama saying, ‘You are a f***ing traitor,’ using those words… ‘You’re a traitor, you allowed foreign boots on our soil telling our military – in this case the Coast Guard – what they can and could not do, and telling us, the citizens of the United States, what we could or could not do,'” he said at a press conference.

At the recent White House Correspondents Assn. dinner, Obama made light of the disenchantment among some Hollywood figures with his performance, noting the disappointment publicly expressed by Matt Damon. “Matt, I just saw ‘The Adjustment Bureau,’ so right back at you, buddy.” One can only imagine what he’d say in response to Fonda’s words.
