President Donald Trump asserted that Rep. Alexandria Ocasio-Cortez (D-NY) was "stupid" after she struggled with foreign policy questions about Venezuela and Taiwan during a conference in Munich."Her performance was horrible," Trump argued during a Thursday gaggle aboard Air Force One. "I was surprised, actually, I didn't know she was stupid."One reporter wondered how Trump would have responded to the questions."I would've just said 'it's none of your business right now,'" the president said. "Because I wouldn't answer that question. I wouldn't respond to a question like that." "It's war. When it comes to war, you don't talk about your strategies. She could have done that briefly. She had no idea. I don't think she knew what Taiwan was," he added. Trump may have forgotten that he previously called Ocasio-Cortez "stupid" last year."Mr. President, don't take your anger out on me - I'm just a silly girl," the lawmaker replied at the time.
