Dear President Obama and Attorney General Holder: We write because of deep concern about reports that you are considering the prosecution of WikiLeaks and Julian Assange for publishing classified cables and other documents. Based on everything we know about these events, we urge you to avoid such action. Our concern flows not from an embrace of Assange's motives and objectives. Indeed, we wish that he would fully disclose his sources of financing and support. But the Constitution protects the right to publish information of important interest to the public. That right has been upheld through decades of American jurisprudence and has served the people well.
