At a private dinner, National Security Advisor H.R. McMaster reportedly mocked Trump's intelligence, stating that his intelligence was comparable to a "kindergartner".
A sixth source told BuzzFeed that they'd heard McMaster disparage the president's intelligence in private in the past, claiming that the National Security Advisor once remarked that Trump lacked the necessary brainpower to comprehend issues discussed at the National Security Council.
"Over a July dinner with Oracle CEO Safra Catz", Buzzfeed reports, "McMaster bluntly trashed his boss". The Trump administration denied the report, with a representative from the National Security Council and an Oracle vice president telling BuzzFeed that McMaster didn't say any of those things about Trump.
Catz was offended by the comments, told Adelson about the conversation, and Adelson associates tried to give the story to the New York Post, but Kushner had called Rupert Murdoch and spiked the story, according to Stone. It was reported in October that Tillerson called Trump a "moron" during a meeting, something the secretary of state later refused to deny ever saying. Due to their perceived influence over the president, both men and in particular McMaster are widely distrusted by Trump's base and some loyalist aides and former staffers, and have been the perceived target of attacks in the press.
"None of the statements attributed to General McMaster were said", Oracle senior VP for government affairs Ken Glueck told BuzzFeed News. A spokesperson for the National Security Council said the story was "false".
The general is also reported to have criticised other members of Mr Trump's administration, including secretary of defense James Mattis, former strategist Steve Bannon and Mr Trump's son-in-law Jared Kushner. "It's like they're preparing to deal with a child", a source told the magazine. Last year, she joined Trump's transition team ahead of his inauguration as president.
The sources who claimed to have heard about the conversation from Catz, said she considered McMaster's comments "jaw-dropping" and "inappropriate".
Catz has been mentioned as a possible Trump appointee.
