Moreover, Mr. Trump’s oldest friends say it is difficult for him to distinguish between large and small slights — or to recognize that his office comes with the expectation that he moderate his behavior.
And his fiercest, most savage responses have almost always been to what he has seen on television.
”Morning Joe,” once a friendly bastion on left-leaning MSNBC, has become a forum for fiery criticism of Mr. Trump. One adviser to the president accused the hosts of trying to “destroy” the administration over several months.
After lashing out at Mr. Scarborough and Ms. Brzezinski at one point last summer, Mr. Trump told an adviser, “It felt good.”
Even before he began his campaign two years ago, Mr. Trump showed a disregard for civility when he made critical remarks on television and on social media, particularly about women.
