Former President Donald Trump allegedly vowed he would never come to Europe’s rescue if the continent were to be attacked, French European Commissioner Thierry Breton said Tuesday at an event in the European Parliament.

Breton said the comments came during a tense 2020 meeting at the World Economic Forum in Davos, Switzerland, where European Commission President Ursula von der Leyen was the recipient of Trump’s warning. Former EU trade chief Phil Hogan was also present, according to Breton.
