Top Trump adviser Elon Musk indicated on Saturday that he hopes the United States and Europe reach a “zero tariff situation,” just days after President Donald Trump‘s “Liberation Day” announcement slapped 20% tariffs on the European Union.

Calling into an event hosted by Italian Deputy Prime Minister Matteo Salvini, Musk addressed the recent Trump tariffs, saying, “I hope it is agreed that both Europe and the United States should move, ideally, in my view, to a zero tariff situation, effectively creating a free trade zone between Europe and North America.”
