"If Trump is upset Rex Tillerson called him a moron, wait till he finds out what the rest of the country has been calling him," the host of "Jimmy Kimmel Live!" said.

"He's going to be mad."

NBC News reported Wednesday said Tillerson nearly resigned over the summer amid fierce policy disputes with the White House, and Vice President Pence had to intervene to calm tensions.

Tillerson during an impromptu news conference at the State Department denied he has ever considered resigning. 

Kimmel said Wednesday that Tillerson, after knowing Trump saw the report, had to call a quick press conference to "address it before our 5-year-old president had a temper tantrum."

The late-night host mocked Tillerson for saying he has never considered leaving his post.

"If you work in the Trump White House and you haven't considered leaving, you're either asleep or you're Ben CarsonBenjamin (Ben) Solomon CarsonVA slashes program that helps homeless veterans obtain housing: report Homelessness rises for first time since recession Moving the US embassy to Jerusalem is the right call MORE," Kimmel said.

This is the first administration where Cabinet secretaries "regularly hold press conferences to announce they're not quitting," the host added.

"It usually happens just before they quit," Kimmel said.

Tillerson also refused to directly answer a reporter's question about a claim that he called Trump a "moron" following a tense meeting with national security officials over the summer.

"I wish he had said, 'Of course I called him a moron,'" Kimmel joked.

"Everyone calls him a moron. We walk around the West Wing going, 'How's the moron today?'"
