A two-faced politician!?! You don't say... Of course they could also do the whole, "there's a faction within the government doing shady stuff, etc." even as a retcon. (I don't recall when they said the POTUS was involved or who said it - they could be lying?)
I do think it'd be funny to see the Pierce's react to the President's statement that Green Arrow was the first hero since Jefferson obviously was active many years prior. A president making untrue statements?!?
