Trump should respond back, “Yes I know what Wakanda is, do you know what FACTS are?”
Good response, short and concise.
My thinking on a response:
“Thank you for the question regarding Wakanda. Now, GET OUT! You are wasting my valuable time, your fellow journalists, and the American peoples’ valuable time, with your ‘fake news’ about a fake country. As you know, Wakanda doesn’t exist. Don’t waste my valuable time with questions about a non-existent country.
If you actually do not know that Wakanda does not exist, other than in comic books, then you should be banned anyway. These sessions are designed to inform the public through journalists who actually have SOME knowledge, no matter how limited, concerning the topic of their questions.
Now, leave and don’t come back until you have learned a little bit of world geography and politics. A six month ban from the Briefing Room should suffice, at least for a start.
Any other questions?”
