Interviewed on the Don Wade & Roma in the Morning show Wednesday, Rep. Mark Kirk (R-Ill.) said that he supports a policy "where if we see Obama there's a shoot-on-sight order."
His office didn't immediately return a call and he clearly, given the context of the conversation, meant to refer to Osama bin Laden.
UPDATE: Politico reports that Kirk apologizes: "On Wednesday, I misspoke when talking with a local Chicago radio program regarding the current presidential campaign of Sen. Barack Obama as well as the status of our anti-terrorism efforts against Osama bin Laden. During the course of this conversation, I mistakenly referred to 'Osama' as 'Obama.' After being alerted to my mistake, I apologized to Sen. Obama for my misstatement and will take extra care to make sure I do not make such a mistake again."
