A warning issued on Truth Social
On July 24, 2026, former U.S. President Donald Trump made a strong statement on his social media platform, Truth Social. He announced his intention to start a new tariff investigation targeting the European Union in response to ongoing legal actions against U.S. tech companies. This threat came in the wake of a specific fine imposed on Google for allegedly giving unfair preference to its own search engine and app store.
The fine, amounting to €890 million (around $1 billion), was described by Trump as part of a larger pattern of "robbing" American businesses. He claimed that total fines against Google had surpassed $18 billion, but did not offer any timeframe or documentation to back this up. EU courts have previously upheld major penalties against the company, such as a record fine exceeding $4 billion, with investigations in that case lasting almost eight years.
Trump's post was lengthy and emotionally charged. He accused the EU of repeatedly targeting American companies, saying the penalties were issued "for no reason at all" and "without explanation." His language reflected a growing frustration with the EU's regulatory actions and the perceived imbalance in trade relations. He framed the situation as a matter of justice, saying the U.S. would no longer allow Europe to "take advantage" of American businesses and taxpayers.
The 301 investigation and its implications
The president's threat to initiate a 301 Investigation marks a shift in strategy following a Supreme Court ruling in 2025. The ruling had limited the president's authority to impose broad tariffs, prompting the adoption of more focused investigations to justify trade measures. A 301 Investigation allows the U.S. to claim unfair trade practices by foreign entities and then impose retaliatory sanctions. This process is based on Section 301 of the Trade Act of 1974.
Trump wrote that the EU would "pay a very big price" for its actions, calling them "illegal and highly unethical." He emphasized that the U.S. would soon introduce tariffs as a response. These actions are part of a broader strategy in which dozens of investigations are already underway. Trump expressed confidence in the outcome, saying, "Stay tuned," and encouraging his followers to remain engaged with the issue.
European response and ongoing tensions
Reactions from European officials and U.S. trade representatives have been varied but largely negative. U.S. Trade Representative Jamieson Greer voiced concerns on Thursday, stating that the EU's enforcement actions undermined efforts at constructive dialogue and posed a "real risk" to transatlantic trade stability. He and others in the administration have been pushing for a more cooperative approach to trade with Europe, but Trump's aggressive stance has complicated matters.
Tensions between the U.S. and EU have escalated further, particularly around the ratification of a fragile trade agreement reached in the previous year. The deal has faced delays as the 27-plus EU member states and Brussels-based institutions struggle to finalize the process. The Trump administration has expressed frustration over the slow progress, which it sees as a missed opportunity for strengthening economic ties.
This conflict has sparked a wave of outrage and confusion among European officials, who view Trump's rhetoric as increasingly erratic and destabilizing. His continued escalation of trade disputes raises concerns about the future of transatlantic relations, with many fearing that the situation could lead to further economic and political friction. The White House remains determined to push forward with its agenda, despite the growing backlash.
