Some are saying Johnson's run is doomed after this misstep. Johnson reportedly said after the interview that he was "incredibly frustrated" with himself.
The campaign has since released a statement. Johnson explained when he was asked about Aleppo, he thought of an acronym, not the Syrian conflict. The statement says, in part: "I blanked. It happens, and it will happen again during the course of this campaign."
