Sean Penn will endorse Kucinich this afternoon at a press conference in San Francisco, a source close to the Hollywood actor said. He will also be speaking on "the Constitution, the media and Dennis Kucinich," the source said. Expect a political speech.
Penn has donated $4,600 to John Edwards' campaign and $2,300 to Kucinich during this cycle, per FEC campaign finance data.
In March of this year, Penn wrote in a WorldNetDaily column that, "As things stand today, I will be voting for Dennis Kucinich, who has fought this war from the beginning. You might say Kucinich can't win. Well, we have an opportunity to re-establish the credibility of democracy as viewed by the world at large."
Penn is set to deliver "a blistering indictment of political leaders and an impassioned endorsement of Presidential proportions," according to a Kucinich press release.
More: "Penn and Democratic Presidential candidate Dennis Kucinich have been close friends for years, but the Kucinich campaign was not involved with Penn in preparing the remarks he plans to deliver today. 'Sean Penn is a good friend, but he's also a very intense, independent-minded person,' said a spokesman for the Kucinich campaign. 'He's going to say whatever he's going to say.'"
