Trump's tweets slam Canada and Trudeau anew from Singapore

President Donald Trump took more swipes at Canada and its prime minister over trade issues as he settled in for a summit with North Korea in Singapore, contending that "Fair Trade is now to be called Fool Trade if it is not Reciprocal."

Trump roiled the Group of Seven meeting in Canada by first agreeing to a group statement on trade only to withdraw from it while complaining that he had been blindsided by Canadian Prime Minister Justin Trudeau's criticism of Trump's tariff threats at a summit-ending news conference.

As he flew from Canada to Singapore Saturday night, Trump displayed his ire via Twitter, which he also employed to insult Trudeau as "dishonest" and "weak."
