Apparently, Secretary of State Rex Tillerson had called Donald Trump a “moron,” even though Trump continues to dismiss the rumor that he said it.

Now, in an interview with Forbes, Trump says that he would win in a battle against Rex when it came to intellect.

“I think it’s fake news, but if he did that, I guess we’ll have to compare IQ tests,” Trump said. “And I can tell you who is going to win.”

Last week, Rex was quick to refute the rumors he’d called the president a moron, addressing NBC News, saying his “commitment to the president” was strong… adding: “I’m not going to deal with petty stuff like that. This is what I don’t understand about Washington. I’m not from this place.”
