But there is one group against which the president can measure himself: The Group of 20, an international forum of leaders from 20 major economies. And Trump just happens to have a trip planned to schmooze with them in Hamburg this week.
Here's a look at what the other leaders of the free world were tweeting out while Trump was disparaging “Crazy Mika” and “Psycho Joe” of “Morning Joe” fame before the start of Thursday's workday and then defending his tweets around dinnertime on Saturday.
Among the tweets:
Justin Trudeau, prime minister of Canada
Last week was the lead-up to Canadian Independence Day, and there's nothing more prime minister-y than donning the Canadian colors and waxing philosophically — and bilingually — about how great America's neighbor to the north is.
And several hours after Trump tweeted about Mika Brzezinski and Joe Scarborough, Justin Trudeau was holding a baby and “chatting with folks in Montague about what's important to them.”
Malcolm Turnbull, prime minister of Australia
It wasn't exactly Australia Day, but this weekend is the first anniversary of the election win of Turnbull and his party.
Turnbull used Twitter to make a case, via video, that this latest trip around the sun has been better and more progressive for Australians than previous ones.
And on the day Trump was posting about the “Morning Joe” hosts, Turnbull was talking about small business and technology on a live Facebook chat.
Vladimir Putin, president of Russia
Putin has not been a prolific tweeter in the past few weeks. A day after Trump's “Morning Joe” moment, Putin posted a picture of himself chatting with former secretary of state Henry Kissinger.
Narendra Modi, prime minister of India
Modi made waves with his hug of Trump last week and is a social media megastar in his own right, but he spent time acknowledging a group and a day that involves the word “accountants.”
And when Trump was declaring war on Scarborough and Brzezinski, Modi was at one of the former homes of Mohandas K. Gandhi, who led the Indian independence movement by employing nonviolent civil disobedience:
Enrique Peña Nieto, president of Mexico
Peña Nieto may not be as prolific a tweeter as other leaders, but on the day Trump was tweeting about “Morning Joe,” Peña Nieto was giving a presidential shout-out to his fellow leader in Colombia.
Translated, it means that Peña Nieto was pleased to return to Colombia to strengthen the connection between the Pacific Alliance members.
Theresa May, prime minister of Britain
May is also not big on Twitter, but she used one of her tweets last week to send her “warmest good wishes” to Muslims celebrating Eid al-Fitr.
