French President Emmanuel Macron pushed back after President Trump asked if France was willing to take back French terrorists who have been captured in Syria and other regions.

"We have a tremendous amount of captured fighters, ISIS fighters over in Syria. And they're all under lock and key, but many are from France. Many are from Germany, the UK. They're mostly from Europe. And some of the countries are agreeing. I have not spoken to the President about that. Would you like some nice ISIS fighters? I can give them to you," Trump said.

Macron acknowledged that some fighters come from Europe — but said most of them are from the Syria and Iraq region.

"Let's be serious: The very large numbers of fighters you have on the ground, are the fighters coming from Syria, from Iraq and the region," Macron said. "It is true that you have foreign fighters coming from Europe, but it's a tiny minority of the overall problem we have in the region." he said.

He continued: "The No. 1 priority — because it's not yet finished — is to get rid of ISIS and terrorist groups.This is out No. 1 priory."
