President Trump in a new interview offered to compare IQ tests with Rex Tillerson after reports that the secretary of State had called him a “moron.”

“I think it’s fake news, but if he did that, I guess we’ll have to compare IQ tests,” Trump told Forbes in an interview published Tuesday.

“And I can tell you who is going to win.”

Tillerson called Trump a “moron” and considered leaving the administration, according to an NBC News report earlier this month.
