Serial liar Donald Trump calls Canadian Prime Minister Justin Trudeau a liar, who is “weak” and “very dishonest” after the media blasts Trump for his unhinged behavior at the G-7 Summit in Canada. Um, a pathological liar calling someone else a liar is just rich….

Trump is now threatening to not endorse the communique he agreed to hours ago because the leaders of the G-6 countries didn’t cave to his bullying but stood their ground.

Trump rage-tweeted:  “Based on Justin’s false statements at his news conference, and the fact that Canada is charging massive Tariffs to our U.S. farmers, workers and companies, I have instructed out U.S. reps not to endorse the Communique as we look at tariffs on automobiles flooding the U.S. market.”

Trump followed that up with another tweet: “PM Justin Trudeau of Canada acted so meek and mild during our @G7 meetings only to give a new conference after I left saying that “US tariffs were kind of insulting” and he “will not be pushed around.” Very dishonest & weak. Our tariffs are in response to his 270% on dairy.”

Um, Canadian autos? Does this moron know the automobiles coming from Canada are from U.S. automakers and mostly working class Americans purchase them?

Flavio Volpe, president of Canada’s Automotive Parts Manufacturers Association, mocked Trump on Twitter: “So…. you’re suggesting using a National Security regulation to charge $8B in tariffs to *American* consumers who buy 1 million cars made by American automakers, containing 60% American parts content, because of the price of milk in Windsor?”

PM Trudeau’s office issued a statement (shameful that they felt compelled to):

The meltdown comes after a photo of German Chancellor Angela Merkel staring down Trump went viral. There is a second photo that shows Managing Director of the IMF, Christine Lagarde and Merkel looking at Trump with disbelief after he showed up late for the gender equality breakfast at the G-7 Summit.
