NYT :
President Trump doubled down on Saturday in his feud with Canada over a television ad that used audio of former President Ronald Reagan denouncing tariffs, saying he would punish the country with an additional 10 percent tariff on its goods .
Mr. Trump had already suspended monthslong trade talks with Canada, the United States’ second-largest trading partner, on Thursday night because of the ad, which had been paid for by Ontario. Though the ad faithfully reproduced Mr. Reagan’s words , just in a different order, Mr. Trump has insisted it was “fraudulent” after the Ronald Reagan Presidential Foundation and Institute said it had made “selective” use of the five-minute original address.
