The Canadian Prime Minister's former policy adviser called Donald Trump a "pathetic little man-child" on over the weekend in response to the president's attacks on Justin Trudeau following the G7 summit.

"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 said.
"Not to sign a statement of solidarity, which stands for everything that we stand for, is a big mistake", Feinstein said.
But Mr. Trudeau also said it was "kind of insulting" the USA had imposed tariffs on steel and aluminum under the guise of national security, noting Canadians stood "shoulder to shoulder" with Americans in overseas wars.
