Ireland Prime Minister Micheál Martin slammed the 20% tariff on imports from across the European Union, calling it "deeply regrettable."

"I strongly believe that tariffs benefit no one. My priority, and that of the government, is to protect Irish jobs and the Irish economy,” he said.

Manfred Weber, the president of the EPP, the European Parliament's largest party, said Wednesday: “To our American friends, today isn’t liberation day — it’s resentment day. Donald Trump’s tariffs don’t defend fair trade; they attack it out of fear and hurt both sides of the Atlantic. Europe stands united, ready to defend its interests, and open to fair, firm talks.”
