‘Cheated and got caught’: Trump accuses Canada of attempting to influence US Supreme Court

“Canada is trying to illegally influence the United States Supreme Court in one of the most important rulings in the history of our Country,” Trump added.

The advertisement, aired by a Canadian organisation, shows Reagan’s long-standing support for open markets and international trade.

The Supreme Court is set to hear arguments on 5 November in a case that will determine the legality of Trump’s sweeping global tariffs, a recurring campaign theme in his current political comeback.

“Canada has long cheated on Tariffs, charging US farmers as much as 400%,” Trump further wrote. “Now they, and other countries, can’t take advantage of the U.S. any longer. Thank you to the Ronald Reagan Foundation for exposing this FRAUD.”

Earlier, on Thursday, Trump escalated the dispute further, calling the video “fraudulent” and announcing the suspension of all trade talks with Canada.

“Tariffs are very important to the national security, and economy, of the U.S.A. Based on their egregious behavior, all trade negotiations with Canada are hereby terminated,” Trump said in a post.

Trump, who earlier this year reinstated import tariffs on Canadian steel, aluminium, and automobiles, has framed his protectionist policies as essential to safeguarding American industry and jobs.

The current remarks come amid rising trade friction between the two neighbours and comments from Canadian Prime Minister Mark Carney, who said he plans to double Canada’s exports to markets outside the US in response to Trump’s tariff threats.
