US Secretary of State doesn't deny calling President Trump 'a moron'

Rex Tillerson called media reports that he had considered resigning "erroneous", but stopped short of denying other reports he had insulted President Donald Trump.

"I reaffirm my commitment to this role and I want to dispel this notion that I have considered leaving," Tillerson said.

The Secretary of State denied speaking with the president earlier today and said his decision to speak was his alone.

"I have not spoken with the president this morning, I believe he is on the way to Las Vegas," he said.

In a short speech that listed his department's reported achievements to date, Tillerson also praised the president's intelligence and leadership before criticising Washington news media.

"He loves America... he's smart, he demands accountability."
