The US president has continued his verbal attacks on some of his country's closest allies following a divisive G7 meeting. Germany came in for its share of lambasting over its NATO contributions.
US President Donald Trump on Monday continued his vitriolic attacks on several close allies in the wake of his early departure from an unusually discordant G7 meeting in Canada, which saw him withdraw US support for a joint communique.
"Fair trade is now to be called fool trade if it is not reciprocal," he wrote in one tweet that then went on to accuse Canada of imposing unfair tariffs on US dairy products.
"Sorry, we cannot let our friends, or enemies, take advantage of us on trade anymore. We must put the American worker first!" he later wrote.
Trump also slammed Europe, writing: "The US pays close to the entire cost of NATO — protecting many of these same countries that rip us off on trade ... The European Union had a $151 billion surplus — should pay much more for military!"
In comments published on Monday, he told newspapers from the Redaktionsnetzwerk Deutschland association that "everyone knows how much is at stake."
In view of threatened US tariffs on car imports, which would particularly affect Germany, Grenell said that he was a "big car fan" and knew how important the industry was.
Grenell is a somewhat contentious figure in Germany. He came under criticism last week for interview comments in which he vowed to "empower" right-wing movements in Europe, drawing fire for what many saw as illegitimate meddling in the democratic process.
