On CNN's "State of the Union", Trump economic adviser Larry Kudlow said the White House was angered by Trudeau's comments during the news conference that Canada would stand up for itself and that recently imposed USA tariffs on steel and aluminum are "insulting".
"He was even willing to sign that socialist communique", Navarro said, referring to the joint statement of G7 nations that Trump ultimately refused to sign, and which was reportedly the result of hard-line American demands.
Kudlow says Trump won't let a Canadian prime minister push him around on the eve of his summit with North Korean leader Kim Jong Un. He will miss the climate session of the G7 summit.
Merkel said the contentious meeting drives home the point she's made for more than a year: that the European Union needs to stand together to increase its clout on the world stage and that the U.S. is a less reliable partner.

Speaking on Saturday during a rare news conference, Trump said he pressed for the G-7 countries to eliminate all tariffs, trade barriers and subsidies in their trading practices. The Canadian leader pulled a "sophomoric political stunt for domestic consumption", Kudlow said, that amounted to "a betrayal". He says that we are the problem with tariffs. "So we are going in with a really positive spirit", the USA president said. "As an example, 270 per cent, nobody knows that".
According to Trump, it's not fair that other countries like Canada and India "have trade barriers against our farmers". Trump imposed tariffs of 25 percent on steel imports and 10 percent on imported aluminum from the European Union on June 1, a move he said was meant to protect US national security.
