Though the specific contents of interactions between foreign leaders are usually kept secret, the details of a series of calls between German Chancellor Angela Merkel and President Donald Trump were recently leaked.
Carl Bernstein from CNN reported that during Trump's conversations with Merkel, one of America's most important European allies, he regularly insulted and bullied her for no obvious reason.
"Some of the things [Trump] said to Angela Merkel are just unbelievable: he called her 'stupid,' and accused her of being in the pocket of the Russians. He's toughest with those he looks at as weaklings and weakest with the ones he ought to be tough with."
Sources report that Merkel stayed calm and on topic as Trump went off the rails, though the German government also tried to keep details of the calls under wraps because the President's behavior was "aggressive" and "problematic."
Twitter was livid at the President's blatant misogyny.
Not only is Trump's behavior offensive, it's also harmful to American interests overseas.
Not only were Trump's alleged insults uncalled for, they were also far from the truth.
It's hard to believe a President acting this way with a close U.S. ally.
Trump's pattern of being unusually harsh toward's female world leaders is well documented.
Bernstein also reported that in talks with U.K. Prime Minister Theresa May, he told her she was a "fool" and "weak."
Who knows which important world leader President Trump will insult next?
