After leaving the summit, Trump tweeted Saturday that he was withdrawing support from a G7 joint communique, while complaining he had been blindsided by Trudeau's criticism of US tariffs at a closing G7 news conference.
"When I got out to the plane, I think that Justin probably didn't know that Air Force One has about 20 televisions".
Navarro's initial remarks came during an interview on Fox News Sunday after the G-7 economic summit in Quebec.
If Donald Trump was counting on Justin Trudeau to bend to USA trade demands after a series of verbal attacks on the Canadian prime minister, it's not working so far.
The Canadian strategy of responding to USA import tariffs of 10 per cent on aluminium shipments and 25 per cent on steel was to announce a set of retaliatory Canadian tariffs on American imports.
Mr. Trump called Trudeau "very dishonest & weak" for his objections to the US tariffs. And, if I may quote the words of the great Bear Bryant, "when you make a mistake you should admit it, learn from it, don't repeat it". "And he's giving a news conference about how he will not be pushed around by the United States".
According to Trump's account of the moment, G7 attendees were content following the conclusion of the meetings until Trudeau took his stand.
On Tuesday, Trump kept up the attack on Trudeau.
Scaramucci said that while the attacks against Trudeau looked personal, they were not meant that way.
"Very childish and unprofessional behaviour", Gorka said. "Canadians, we're polite, we're reasonable, but we also will not be pushed around".
People close to the prime minister reject the suggestion he misread Trump and cite what they say is the president's highly unpredictable nature. He's railed many times in recent days against Canadian import duties of 270 percent on dairy.
It said Canada would "reject disparaging and ad hominem (personal attack) statements by US officials which do a disservice to bilateral relations and work against efforts to resolve this trade dispute".
Freeland said Canada's approach to the trade talks remains unchanged: to work for a win-win-win compromise while being "absolutely resolute in defence of the national interest".
