President Trump attempted Wednesday to discredit an article from NBC News stating Secretary of State Rex Tillerson threatened to leave his post in July and called the president a "moron."

"NBC news is #FakeNews and more dishonest than even CNN. They are a disgrace to good reporting. No wonder their news ratings are way down!" Trump tweeted Wednesday, as he travels to Las Vegas to meet with victims of Sunday night's mass shooting.

"The @NBCNews story has just been totally refuted by Sec. Tillerson and @VP Pence. It is #Fakenews. They should issue an apology to AMERICA!" he said in a second tweet.

According to NBC News, Tillerson threatened not to return to Washington, D.C., from his son's wedding in Texas in July after the president addressed the Boy Scouts of America in West Virginia.

Many criticized Trump's address at the National Scout Jamboree for being too political.

Tillerson was the Boy Scouts' national president from 2010 to 2012, and he reportedly was upset by Trump's comments.

NBC News also reported the secretary of state called Trump a "moron" after a July 20 meeting at the Pentagon, which included members of the president's national security team and other Cabinet offiicals.

Vice President Mike Pence spoke with Tillerson about his frustrations with Trump, according to NBC News, and urged him to work through his differences with the president.

Defense Secretary Jim Mattis and then-Homeland Security Secretary John Kelly, now White House chief of staff, also spoke with Tillerson and urged him to stay on.

Tillerson gave an impromptu statement responding to the NBC News article on Wednesday morning, and disputed he thought about resigning in July.

"The vice president has never had to persuade me to remain secretary of state because I have never considered leaving this post," Tillerson said.

Notably, though, the secretary of state didn't confirm or deny calling Trump a "moron," and instead dodged questions about whether he did.

"I'm not going to deal with petty stuff like that," he said. "This is what I don't understand about Washington. Again, I'm not from this place. But the places I come from, we don't deal with that kind of petty nonsense. And it is intended to do nothing but divide people, and I'm just not going to be part of this effort to divide this administration."
