This week we have been discussing Attorney General Eric Holder’s recent speech at Northwestern University Law School detailing the claim of President Barack Obama that he has the right to kill American citizens based on his inherent authority and the ongoing war on terror. I previously wrote a blog and a column on the issue. Those pieces noted that Holder limited his remarks by referring to targeted killing “abroad.” However, I noted that the Administration’s past references to this power are not so limited. Indeed, the only limits stated by the Administration have been self-imposed standards and what Holder calls “due process” — expressly excluding “judicial process.” Now, FBI Director Robert Mueller has entered the fray. On Wednesday Mueller was asked in a congressional hearing whether the current policy would allow the killing of citizens in the United States. Mueller said that he simply did not know whether he could order such an assassination.
