McCain tweeted on behalf of the nation after a tense G7 summit in Quebec that left Trump and Canadian Prime Minister Justin Trudeausniping at one another. Trump even threatened to withhold endorsement of a joint G7 statement on the meeting.
While Trump initially tweeted about the "great meetings and relationships" in Quebec after he left the summit early, Trudeau later vowed at the meeting that Canadians "will not be pushed around" in a trade face-off with the United States. He said that Canada is "absolutely" ready to impose retaliatory tariffs after Trump last week initiated a 10 percent aluminum and 25 percent steel tariff on imports from Mexico, Canada and the European Union.
Trump fired back that he was surprised by the prime minister's comments because he seemed so "meek and mild" at the summit. He also called him "very dishonest," but failed to explain what he meant.
At the summit, Trump complained that allies were treating America "like a piggy bank" and he vowed to stick by his tariffs. But he then suddenly suggested instead that the countries consider dropping all tariffs.
