US President Donald Trump on Friday threatened to launch a tariff investigation against the European Union, marking a sharp escalation in tensions between the two economic powers over the bloc's regulatory enforcement against major American technology companies.
The president's warning came in direct response to the EU's most recent antitrust penalty — an €890 million (approximately $1 billion) fine handed down on Thursday against Google for allegedly giving unfair preference to its own search engine and its Play app. Trump also referenced broader enforcement actions that have targeted companies including Apple, Amazon, and Meta.
Trump Lashes Out on Social Media
Taking to his Truth Social platform, Trump accused the European Union of "taking direct aim at GREAT American Companies." He listed a series of fines — or cumulative totals of penalties — that he claimed were levied "for no reason at all" and "without explanation," characterizations that misrepresent the EU's formal antitrust proceedings.
Trump specifically highlighted the latest Google penalty and asserted that the company's total fines had reached "over 18 Billion Dollars," though he provided no specific timeframe or supporting evidence for that figure. EU courts did recently uphold a record fine exceeding $4 billion against Google, the culmination of a review process that spanned nearly eight years. That ruling represented one of several antitrust cases brought against the search giant in recent years.
Declaring that the United States would not serve as a "PIGGYBANK" for Europe, Trump announced his intention to "immediately initiate a 301 Investigation" into what he described as the "ROBBING" of American companies and, by extension, the American taxpayer. He warned that the EU would "pay a very big price for this illegal and highly unethical conduct" and predicted that the penalties would be "entirely reversed" alongside a "substantial TARIFF."
What Is a Section 301 Investigation?
The 301 Investigations have become the primary mechanism Trump relies on to impose tariffs, following a Supreme Court ruling that he had overstepped his authority with the sweeping near-global levies he announced on what he termed "Liberation Day" in 2025. The process derives from Section 301 of the Trade Act of 1974, which permits the United States to internally determine that a trading partner has engaged in unfair trade practices and subsequently impose retaliatory sanctions.
Dozens of such investigations are reportedly already in the pipeline, making the 301 framework a cornerstone of the administration's current trade enforcement strategy.
