“No wonder others are keeping silent about Assange's antics,” Palin emailed. “This is what happens when you exercise the First Amendment and speak against his sick, un-American espionage efforts.”

Palin has criticized Wikileaks founder Assange, writing on Facebook that his “past posting of classified documents revealed the identity of more than 100 Afghan sources to the Taliban. Why was he not pursued with the same urgency we pursue al-Qaeda and Taliban leaders?...Assange is not a 'journalist' any more than the 'editor' of al-Qaeda's new English-language magazine Inspire is a 'journalist.’ He is an anti-American operative with blood on his hands."
