Speaking to reporters from the press briefing room just after 12.30pm today New Zealand time, Trump repeated false claims that he had won many states only to have the results "whittled" away.
Cooper had harsh words for Trump after the address.
"That is the president of the United States. That is the most powerful person in the world. We see him like an obese turtle on his back flailing in the hot sun, realising his time is over."
All three major broadcast television networks in the US cut away from the speech as the president started making false claims, according to The New York Times.
