- "Prime Minister Trudeau is being so indignant, bringing up the relationship that the USA and Canada had over the many years and all sorts of other things. but he doesn't bring up the fact that they charge us up to 300% on dairy - hurting our Farmers, killing our Agriculture!" Those remarks then sparked a Twitter outburst from Trump in which he called Trudeau "so indignant".
But Arizona Sen. John McCain, who is often aligned with Graham, pushed back Saturday against Trump's refusal to sign the G-7 statement.
Trump has consistently said that countries that have a trade surplus with the USA - meaning they export more to the United States than they import - are "taking advantage" of the US.
"He learned, that's going to cost a lot of money for the people of Canada", Mr Trump said in Singapore on Tuesday, after his landmark meeting with North Korea leader Kim Jong-un. "Then Justin acts hurt when called out!" According to a Canada release, they make nearly 100 Billion Dollars in Trade with USA (guess they were bragging and got caught!).
Trump advisers also took up the attack in appearances on Sunday's news shows, leveling more withering and unprecedented criticism against Trudeau, branding him a back-stabber unworthy of Trump's time. He had other things, bigger things on his plate in Singapore, he said.
There had been widespread speculation that the G-7 nations would not issue a joint communique that included the United States due to deep differences between Trump administration and close American allies on trade. And what did Trudeau do as soon as the plane took off from Canadian airspace? "That will not stand".

"Kim must not see American weakness", he told CNN.
Canada's foreign minister Chrystia Freeland said her country "does not conduct its diplomacy through ad hominem attacks".
Navarro's comments came after Trudeau said Canada would push back on tariffs that Trump plans to impose on Canadian steel and aluminum. "We don't think that that is a useful or productive way to do business".
Trump says Trudeau "probably didn't know that Air Force One has about 20 televisions". Trump tweeted on Sunday. Can't do it in person. "We just shook hands!"' Mr Trump said.
Trudeau has vehemently opposed the imposition of tariff on U.S. import of Canadian steel and aluminium and has threatened with retaliatory measures.
"What this has done quite frankly, Canadians in general are much more interested and acutely aware that we need to do more to expand our markets". You are his friend only as long as you're subservient.More news: Macedonia makes name change deal with Greece
