Some in France have also started using the evidence of the increasingly tactile relationship between Macron and Trump to point out what they consider to be uncomfortable similarities between the two presidents, especially on immigration.
On Tuesday, the same day Macron arrived in Washington, France's National Assembly passed his hotly contested migration bill, which would, among other things, allow authorities to imprison illegal immigrants for one year and double the amount of time during which asylum seekers could be detained by police, from 45 days to 90.
In the aftermath of the vote, one parliamentary deputy from Macron's party went so far as to announce he would be leaving the President's centrist faction.
Macron's immigration policy had already alienated some of his supporters in recent months.
In January, the French magazine L'Obs, formerly known as Le Nouvel Observateur, which was favourable to his candidacy throughout his presidential run, placed him on the cover behind a barbed-wire fence: "Welcome to the Country of Human Rights," the headline read.
Macron's perceived similarity with Trump on the issue has only fanned the flames of outrage.
In a bilateral press conference, Trump underscored these apparent points of intersection, in remarks about "uncontrolled migration."
"I know that you face similar challenges, and, Mr President, I admire the leadership you have shown in addressing them in a very honest and direct fashion - and not always popular," Trump said, addressing Macron.
"Both of our elections owe much of the success to the desire of everyday citizens to be heard, to be listened to and to have control over their own nations and their own futures," Trump said.
These compliments did not play well in France, where Macron - especially in comparison with Marine Le Pen, his far-right opponent in last year's election - was largely expected to assume a softer line on the migration question.
"Emmanuel Macron received the congratulations of Donald Trump in person on his migration policies," announced La France Insoumise ("France Unbowed"), a prominent left-wing faction, via Twitter. "Support that speaks volumes . . . "
Jean-Luc Mélenchon, the leader of La France Insoumise, added: "Lamentable alignment of Macron with Trump's line."
In an informal, town hall with students at George Washington University today, Macron was asked about his migrant policy. He defended his views by emphasising the difference between asylum seekers and economic migrants.
"I want my country to welcome the maximum number of people entitled to be accepted, when they are risk in their country," Macron said in English, sleeves rolled up.
"Ninety percent of people coming from Africa are not coming to Europe because of these kind of political risks - they are coming from economic risks. You cannot accept everybody. That's not a sustainable burden for French society."
