Sen. Bob Corker, the Tennessee Republican who chairs the Foreign Relations Committee, said that "you'd have to be not paying attention to know that we've damaged relations" with Canada.
Trump had delivered a stark warning to America's trading partners not to counter his decision to impose tariffs on steel and aluminum imports.
The Republican Corker has criticised Trump for attacking a vital ally, and lashed out at leaders in his own party for refusing to schedule a vote on his measure to let Congress approve or reject any tariffs imposed by the United States president.
Trudeau struck a steady-as-he-goes pose after Trump's latest dig, telling reporters, "I'm going to stay focused on defending jobs for Canadians and supporting Canadian interests". "And I left the meeting, and I'll be honest, we're being taken advantage of by virtually every one of those countries very seriously".
"It would be with regret but it would be with absolute clarity and firmness that we move forward with retaliatory measures on July 1, applying equivalent tariffs to the ones that the Americans have unjustly applied to us", said Trudeau.
She said the answer to the dispute was simple: "The U.S. has to remove these unfair, illegal tariffs from Canada and from its allies".
Canada was insulted by Trump's notion, and when he imposed a 25-percent tariff on Canadian steel and a 10-percent tariff on aluminum. "But if history tells us one thing, it's that no one nation's preeminence is eternal", she said.
She called the American tariffs a "naked example of the United States putting its thumb on the scale, in violation of the very rules it helped to write".
"[Trudeau] really kind of stabbed us in the back", Kudlow said.
One of the ways to do that would be to add the COP21 Paris Agreement to the list of multilateral environmental agreements (MEAs) to which parties must adhere and enforce.
While Trump expressed surprise at Trudeau's remarks, his comments were largely in line with what Canadian officials had said since Trump's announcement of tariffs. Climate risk, carbon taxes, gender issues or any of the more ethereal "strange brew" advocated for by Prime Minister Trudeau in NAFTA are not in keeping with U.S. policy.
"Given Canadians" well-known instability-their currency is called the "loonie'-there can be only one solution: We are going to build a wall from ME to Alaska-and Ottawa is going to pay".
Freeland huddled behind closed doors with Senate Foreign Relations chairman Bob Corker and other senators on the committee eager to fix the fraying relationship after President Donald Trump cited national security interests for slapping punitive tariffs on Canadian steel and aluminum.
The Trump-Trudeau tiff over G7, that is now the subject of much public commentary, as reported by the New York Times on June 9, 2018, is set on a backdrop of a provocative climate change deal made by Canada with France, says Friends of Science Society.
