Compromising U.S. national security is always a sure-fire way to become a hero of the left.

LONDON — Prominent Hollywood figures are among those who signed a letter in support of WikiLeaks founder Julian Assange’s request for political asylum in Ecuador.

The petition, which a group called Just Foreign Policy delivered to the country’s embassy here where Assange sought refuge last week, was signed by Michael Moore, Oliver Stone, Danny Glover, Bill Maher and author Naomi Wolf, among others, it said.

Just Foreign Policy said it delivered the letter with more than four thousand signatures from Americans urging Ecuardo’s president Rafael Correa to approve Assange’s asylum request.

Assange, who is Australian, walked into the Ecuadorian embassy last week in his latest attempt to avoid extradition to Sweden where he would face sex assault charges.
