Donald Trump's trade adviser publicly called attention to the President's lack of knowledge on trade deals in an incident at the White House last week.
Robert Lighthizer is the man in charge of leading trade negotiations between the United States and China.
In a press conference on Friday, he and Trump disagreed on the definition of a memorandum of understanding, one of the first steps in establishing a legally binding contract between two parties.
Despite Lighthizer's explanation, Trump insisted that he did not like MOUs because "they don't mean anything".
The exchange eventually culminated in Lighthizer remarking that, from now on, the term 'trade agreement' would be used instead.
Sources later said that Trump was unhappy with Lighthizer's public challenge and had been left embarrassed by it.
Cal Thomas and Marion McKeone discussed this and more from the US, including Michael Cohen's expected admission of Trump's criminal conduct while in office, and the upcoming Trump-Kim summit in Hanoi.
