White House trade adviser Peter Navarro lit into Canadian Prime Minister Justin Trudeau on Sunday, saying there's a "special place in hell" for a world leader who double crosses President Donald Trump.

"There's a special place in hell for any foreign leader that engages in bad-faith diplomacy with President Donald J. Trump and then tries to stab him in the back on the way out the door," Navarro told Chris Wallace on "Fox News Sunday." "And that's what bad-faith Justin Trudeau did with that stunt press conference."


When asked whether the president shares his views, Navarro said the sentiment came “right from Air Force One.“ At the time of the interview, the president had just landed in Singapore for his upcoming summit meeting with North Korean leader Kim Jong Un.

"To my friends in Canada, that was one of the worst political miscalculations of the Canadian leader in modern Canadian history," Navarro added. "All Justin Trudeau had to do was take the win."

The president slammed Trudeau via Twitter on Saturday, calling out his counterpart for acting "meek and mild." Trump and the White House are upset that Trudeau told reporters that Canada would stand firm when it came to new U.S. tariffs and “not be pushed around."

Navarro added that the joint G-7 communique, a statement of shared beliefs that usually accompanies the close of the meeting, was a "socialist document." Trudeau told reporters that the statement was supported by every member, but Trump's Twitter message Saturday withdrew U.S. support for the communique.

"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 our U.S. Reps not to endorse the Communique," Trump wrote on Twitter.
