The Justice Department white paper" purporting to authorize Obama's power to extrajudicially execute US citizens was leaked three weeks ago. Since then, the administration - including the president himself and his nominee to lead the CIA, John Brennan - has been repeatedly asked whether this authority extends to US soil, i.e., whether the president has the right to execute US citizens on US soil without charges. In each instance, they have refused to answer. Brennan has been asked the question several times as part of his confirmation process. Each time, he simply pretends that the question has not been asked, opting instead to address a completely different issue. It's really worth pausing to remind ourselves of how truly radical and just plainly unbelievable this all is. What's more extraordinary: that the US Senate is repeatedly asking the Obama White House whether the president has the power to secretly order US citizens on US soil executed without charges or due process, or whether the president and his administration refuse to answer? That this is the "controversy" surrounding the confirmation of the CIA director - and it's a very muted controversy at that - shows just how extreme the degradation of US political culture is.
