"I know it didn't look friendly", Trump said.
"On his comments, as I said, I'm going to stay focused on defending jobs for Canadians and supporting Canadian interests". "We just shook hands!'" Trump said Tuesday.
Both aides accused Mr Trudeau of betraying Mr Trump when he gave a news conference after the U.S. president had departed. And, if I may quote the words of the great Bear Bryant, "when you make a mistake you should admit it, learn from it, don't repeat it". "You can't do that".
Trudeau has yet to comment on the Trump administration's criticism.
As he flew from Quebec to Singapore for a meeting with North Korean leader Kim Jong Un, Trump responded to Trudeau's comments on Saturday by withdrawing the United States from a joint document that summarized what was agreed to at the G-7 summit. He also said Canada "will not be pushed around".
One particular source of his ire recently has been Canada's supply management system, which levels tariffs of up to 300 per cent on imported dairy products.
"Obviously we support the continuing efforts by the president on North Korea", the prime minister said.
The attacks against Canada didn't end there, on Sunday, economic advisor Larry Kudlow accused Canada of stabbing the U.S.in the back.
White House Director of the National Trade Council Peter Navarro apologized Tuesday for saying there was a "special place in hell" for Canadian Prime Minister Justin Trudeau after he conducted perceived "bad faith diplomacy" with President Donald Trump.
The foreign affairs minister spoke to reporters in Ottawa and offered a markedly different tone from the attacks lobbed at Canada, one of the United States' closest allies, this weekend by President Trump and other members of his administration.
Bruce Heyman, a former USA ambassador to Canada, said Mr Navarro had "crossed a line".
"I thought (Navarro) should've kept his big mouth shut because I don't think that helps us inform policy and I think frankly it was out of line", Republican Sen. "I think we're in a hard place now, I'd like to see this thing settle down". Perhaps they were trying to show the power they have. It's either 17 but could actually be 100 billion.
He said Trump agreed with the fairly generic trade language in the communique drafted by the G7 leaders, who are traditionally America's closet allies. During the Second World War, the US joined Canada and the Allied forces to defeat the Axis powers. The U.S. had a trade surplus with Canada of $8.4 billion past year, according to the Office of the United States Trade Representative.
