U.S. House Judiciary Chair Jim Jordan has urged EU antitrust chief Teresa Ribera to clarify the enforcement of the European Union’s Digital Markets Act (DMA), suggesting it unfairly targets American tech giants. In a letter co-signed by Scott Fitzgerald, Jordan raised concerns that the DMA imposes excessive regulations on U.S. companies, giving European firms an advantage.

The request follows President Donald Trump’s recent memorandum, which signaled his administration’s intent to scrutinize the EU’s DMA and Digital Services Act, citing potential restrictions on how American companies operate in Europe. The DMA, aimed at ensuring fair competition, imposes strict rules on tech giants like Alphabet, Amazon, Apple, Meta, Microsoft, and ByteDance.

Jordan and Fitzgerald criticized the DMA’s penalties—up to 10% of global annual revenue for violations—arguing that they serve as an indirect tax on American businesses and force compliance with European regulations worldwide. They also warned that certain DMA provisions could benefit China by requiring companies to share valuable proprietary data.

The lawmakers have requested Ribera to brief the judiciary committee by March 10. The European Commission has denied claims that its regulations specifically target U.S. companies. Ribera recently stated that the EU should not be pressured into changing laws already approved by lawmakers.

As the debate intensifies, the impact of these regulations on U.S. tech firms and global competition remains a key issue. The European Commission has yet to respond to the lawmakers’ letter.
