"Please be reassured we've convinced him that we had to stay on in the long-term", Macron said. "We convinced him it was necessary to stay", Macron said in an interview broadcast by BFM TV, RMC radio and Mediapart online news. Macron said officials helped narrow the president's focus for potential strikes after he had "gotten a little carried away over tweets", Reuters reported.
Macron says he changed Trump's mind in a phone call before the airstrikes on Friday night.
"The U.S. mission has not changed - the President has been clear that he wants United States forces to come home as quickly as possible", press secretary Sarah Sanders said in a statement. The US, UK and French strikes must "restore the absolute ban on chemical weapons, which is engraved in the marble of global conventions", Mr Delattre said.

The French leader will make a state visit to the USA next week and is scheduled to travel to Russian Federation next month.
Saturday's strikes on Syria were the first major military operation since Macron's election in May previous year.
Macron reaffirmed that there was proof of chemical attacks, adding: "We had reached a point where these strikes were necessary to give back the [international] community some credibility". "He [Russian president Vladimir Putin] has understood it's not the case any more".
Macron added that Russian Federation, which backs Assad politically and militarily, had made itself complicit in the Syrian government's actions.More news: Musk insists Tesla does not need more capital
The French president nevertheless said he wanted to engage in dialogue with all parties involved, including Moscow, in order to find a political solution for Syria. "It is worldwide community that has intervened, and has done so in an extremely precise way", he added and reiterated that France considers that it has sufficient evidence that Damascus is behind use of chemical weapons in city of Duma a little over a week ago.
Macron had warmer words for Turkey.
At a meeting of the Organisation for the Prohibition of Chemical Weapons (OPCW), UK representative Peter Wilson said: "Russia has argued that the attack on Douma was somehow staged, or faked".

Macron, criticised by the far-left and far-right and part of the conservatives over the attacks, said France, Britain and the United States had "complete worldwide legitimacy to act".
