::::wait I just realized you said he "looked" stymied which implies a video. The reference here is an audio clip. In any event, look, a reliable source for this would be text: the Guardian, the Washington Post, the Wall Street Journal, The New York Times, CBC, NPR, possibly Al-Jazeera, LA Times, possibly Salon depending, possibly Politico depending, Daily Beast for the quote itself would be fine... does that help? Maybe some others but those would go to the next level of a serious evaluation...
