"Let me correct a mistake I made", Mr Navarro said at a Wall Street Journal conference. "I mean seriously, Russia, who took over Crimea, all the violence that's taken place in Ukraine, the poisoning of people in the United Kingdom, the influence in our election this last time period", Heyman recounted.
Trump said he chose to back out of the G7 communique after watching Trudeau's closing summit news conference, at which he warned that Canada would not be pushed around on tariffs - a point the Canadian prime minister had made several times before.
Days later, Trump said that he had left the summit at that stage and was aboard Air Force One en route to Singapore when Trudeau gave the press conference.
Mr Trump left the meeting early before firing off a series of scathing tweets about his Canadian counterpart after Mr Trudeau said his country would not be pushed around by United States trade restrictions.
Mr. Trump responded that Mr. Trudeau's comments were "dishonest and weak", and dispatched two of his advisers to attack the Prime Minister on television the next day.
Don't Worry, The Minnesota Tower Raccoon Survived
A raccoon is finding itself in deeper and deeper - er, higher and higher - trouble as it climbs downtown St. By Tuesday evening, the critter had scampered up to the 23rd floor for a long nap.
"PM Justin Trudeau acted so meek and mild", he tweeted. "And that's what bad-faith Justin Trudeau did with that stunt press conference".
At his closing G-7 press conference on Saturday, Trudeau called USA steel and aluminum tariffs "insulting" and pledged to proceed with previously announced retaliatory tariffs.
On Sunday morning Navarro and Trump's director of the National Economic Council, Larry Kudlow, piled on the criticisms. But the president broadsided his allies after leaving the meeting by disavowing a joint statement the USA had agreed to, criticizing Trudeau and vowing tariffs on automobiles.
And Roland Paris, a former foreign policy adviser to Mr Trudeau, jabbed at Mr Trump on Twitter: "Big tough guy once he's back on his airplane". It was very friendly.
Navarro's apology was unusual in that President Donald Trump and his aides have seldom walked back harsh and even incorrect statements. "I think he's good".

Trump escalated a trade war earlier this month when he announced he would impose tariffs on steel, aluminum and other metals from Canada, Mexico and the European Union.
The insults stemmed from a closing G7 press conference on Saturday in which Trudeau called U.S. steel and aluminum tariffs "insulting" and pledged to proceed with previously announced retaliatory tariffs.
Hayden also scoffed at the idea that Trump's actions were part of an elaborate strategy as the president prepares for an historic summit with North Korean leader Kim Jong Un on Tuesday. "I think within the first minute I'll know", Trump said. "We just shook hands!'" Trump said Tuesday.
Trump said he was retaliating against Canada with countervailing tariffs, saying of Trudeau: "He learned that's going to cost a lot of money for the people of Canada".
"The president, coming late, stands before the cameras and says, "Why don't we add Russian Federation to the group". The relationship between the two leaders appears to have soured since comments were made regarding US tariffs on Canadian steel and aluminum imports.
