Julian Assange popped his head out of the Ecuadorean Embassy in London today, making his first public appearance in two months and calling on President Obama and the United States to "do the right thing" and "renounce its witch hunt against WikiLeaks." Speaking from the balcony of the embassy, Assange thanked his supporters, "the courageous South American nation" of Ecuador, and said that he had taken "a stand for justice," reports Sky News. The comments are his first since Ecuador granted him asylum on Thursday, notes the AP. (More Julian Assange stories.)
