Trump came to France beset by allegations of Russian interference in the 2016 US election, with emails released on Tuesday suggesting his eldest son welcomed an offer of Russian help against his father's Democratic rival Hillary Clinton.
By contrast, he said: "Theresa May was seen as rushing to Washington more ore less desperate to get Trump's attention". Flanked by the Melania Trump and Brigitte Macron, Trump grasped Brigitte's hand with his left hand even as he continued to hold the French president's hand with his right.
The US president withdrew from the 2015 Paris climate agreement last month, citing moves to negotiate a new "fair" deal that would not disadvantage US businesses.
Trump then, with his free hand, engages Mrs Macron in a handshake too, simultaneously shaking the hands of both Macrons at once.
Several highlights of the parade put the United States in the spotlight.
Macron hopes to act as Trump's bridge to Europe, his advisers have said, as other leaders here effectively isolate the USA on a set of key issues. He has also said nobody would vote for Carly Fiorina, his Republican rival for the nomination, because of her appearance.
During his trip, Mr. Trump found that leaving the country did not also mean leaving behind questions surrounding Russian meddling in the 2016 presidential election. "You're going to have a very, very peaceful and handsome Paris".
"You're in such good shape", the 71-year-old says in the footage, before turning to Mr Macron to marvel: "She's in such good physical shape".
"Beautiful", Trump told the French President's wife on Thursday, who was standing next to US First Lady Melania Trump.
He said he hopes to build on the relationship with Mr. Putin to end more suffering in Syria.
