A number of other Trump officials and the president himself also lashed out at the Canadian prime minister following the Group of Seven (G-7) summit in Canada last weekend.

Trump refused to sign the G-7 joint agreement after Trudeau severely criticized Trump following the international summit.

Trump officials have suggested that Trudeau double-crossed Trump by criticizing him on television after he left the gathering.

Trump in a tweet slammed the leader of one of America’s longest-standing allies.

“PM Justin Trudeau of Canada acted so meek and mild during our @G7 meetings only to give a news conference after I left saying that, ‘US Tariffs were kind of insulting’ and he ‘will not be pushed around,’ ” Trump tweeted on Saturday.

“Very dishonest & weak,” the president added. “Our Tariffs are in response to his of 270% on dairy!”
