'I used language that was inappropriate and basically lost the power of that message, ' says Navarro.
With diplomatic tensions between USA and Canada rocked by recent comments about trade by president Donald Trump and his advisers, some Americans are finding ways to acknowledge Canada's other exports in popular culture.
Before the apology, some US lawmakers on Tuesday questioned the strong language the White House and Trump have used toward Canada in contrast to the praise he gave North Korea at Tuesday's summit in Singapore.
Unbowed, Trump tweeted anew Monday morning from Singapore, repeating his criticism of USA trade policies with Canada - he also took aim at Germany - in a multitweet rant that went beyond 200 words all told.
Trudeau, who had said at the news conference that Canada would retaliate for new USA tariffs, didn't respond to questions about Trump when the prime minister arrived at a Quebec City hotel Sunday for meetings with other world leaders.
But today he apologized for using language that counteracted his goal of sending a signal of strength. He says one thing, then says the complete opposite when his own words make him look bad.
Here at home, Trudeau refused to engage, telling reporters on his way into cabinet that he supports the North Korea talks but wouldn't talk about the president's latest threats to Canada.
While Trudeau himself has kept a low profile since the USA attacks, Canadians incensed on his behalf have zeroed in on a pocketbook response. "I don't understand the obsession with trade relations with Canada", he said on Fox's "Sunday Morning Futures", given that Canada is the biggest single buyer of American goods and services in the world.
Trump took to Twitter to slam Justin Trudeau while en route to Singapore.
Canadian lawmakers unanimously voted to oppose the U.S.' "illegitimate tariffs" on Canadian steel and aluminum and condemned disparaging statements made by the Trump administration about Canada.
Music critic David Wild reacted to the conflict on Sunday by encouraging others to consider what Canada has given its US neighbours.
The coordinated attack against Trudeau from the USA officials, not to mention Trump's tweets calling Trudeau "weak" and dishonest, has led former US ambassador to Canada Bruce Heyman to conclude the White House is trying to make Canada the scapegoat for troubled NAFTA negotiations.
Trump also continued to denounce Canada's system of supply management to protect the domestic dairy, egg and poultry industry, which levels tariffs of up to 300 per cent on American imports of those products. "Europe will always be driven by our shared values of freedom, democracy, the rule of law and the respect of human rights, and we will continue to be at the heart of the global agenda, promoting jobs, growth, free and fair trade, clean environment, gender equality, and development aid". He added that Canada will "move forward with retaliatory measures" on July 1 against the U.S. That warning is apparently what set Navarro off.
