"State of the Union" host Jake Tapper asked Kudlow what right Trump and other US officials had to be offended by Trudeau's comments, given the dispute.
In a flurry of tweets from Air Force One, en route to Singapore for a historic nuclear summit with North Korea's Kim Jong Un, Trump accused the summit host, Canadian Prime Minister Justin Trudeau of being "very dishonest".
Trump, who departed the summit early, also accused Canadian Prime Minister Justin Trudeau of being "very dishonest" in his condemnation of United States tariffs. "Canadians are polite, we are reasonable, but we will also not be pushed around". Trump tweeted that Trudeau was "very dishonest & weak".
Mr. Trump wrote (below).
And EU leaders at the summit also reportedly told Trump they had no choice but to impose their own tariffs against the U.S.
"He really kind of stabbed us in the back", Mr. Kudlow told CNN's State of the Union.
The president slammed Trudeau via Twitter on Saturday, calling out his counterpart for acting "meek and mild". "But President Trump has every right to push back publicly on this Trudeau amateur scheme".
Friday morning he was spitting again: "Canada charges the US a 270% tariff on Dairy Products!" "I don't understand the obsession with trade relations with Canada", he said on Fox News, given that Canada is the biggest single buyer of American goods and services in the world.
"However, later the same day, Trump said he had instructed the US House of Representatives not to endorse the communique due to the statements made by Trudeau, who called the recent US metal tariffs insulting" and pledged to proceed with retaliatory measures. "We will stand by them and anyone who would depart from them, once their back was turned, shows their incoherence and inconsistency", the statement said.
Peter Navarro watches as President Donald Trump speaks before signing Section 232 proclamations on steel and aluminum imports in the Roosevelt Room of the White House on March 8, 2018 in Washington, D.C. "He was even willing to sign that socialist communique". And then Trudeau starts blasting him in a domestic news conference? "Kim must not see American weakness".
The Illinois Democrat acknowledged that Trudeau's tough talk with Trump may play well domestically, but said it would have longer-term negative implications. He said US representatives will examine the tariffs on automobiles coming into the country and bemoaned the Canadian tariffs that affect American companies and farmers.
