USTR
Cabinet-level US trade body that negotiates agreements, enforces trade law, and advises the President.
USTR, under Jamieson Greer, opened a fresh Section 301 investigation into EU digital rules on 24 July 2026, a day after calling Brussels's roughly €890m Google DMA fine a source of massive uncertainty for US exporters.

European Tech SovereigntyBackground
The Office of the United States Trade Representative is the Cabinet-level body responsible for developing and coordinating US international trade, commodity and direct-investment policy. It negotiates trade agreements, represents the US in WTO disputes, and holds statutory authority under Section 301 of the Trade Act of 1974 to investigate foreign trade practices and recommend tariffs.
Created under the Trade Expansion Act of 1962 as the Office of the Special Trade Representative and elevated to full Cabinet rank in 1979-80, USTR employs around 200 specialist trade officials across Washington, Geneva and Brussels on an annual budget of roughly $73m. It led the USMCA renegotiation, publishes the annual Special 301 Report on intellectual-property enforcement, and has been the counterparty to EU disputes over steel and aluminium tariffs and agricultural-market access.
The investigation still has no public docket
USTR opened its Section 301 investigation into EU digital rules on 24 July 2026, the day after Jamieson Greer called Brussels's Google DMA fine a source of massive uncertainty for US exporters. A Federal Register query on 4 August for Section 301 digital documents published since 24 July returned nine items, none concerning EU digital enforcement.
Ten days into the investigation, no docket record confirms the probe formally exists in the administrative sense, even as Greer's public statements treat it as active. Beyond this single docket, Greer took USTR through one of its most active enforcement stretches in years, deploying Section 301 simultaneously against EU digital-rules enforcement and supply-chain labour practices within the same 24-hour window.
USTR answers a fine with a probe
The Commission's €890m DMA fine against Google, announced 23 July 2026, drew an immediate USTR response naming it a trade irritant rather than a purely competition-law matter. That framing elevates the DMA dispute from an EU regulatory action into a live transatlantic trade question.
USTR's counterparty role across every significant EU-US trade friction, from steel and aluminium tariffs to agricultural-market access, means the digital-rules investigation sits inside an established pattern of using Section 301 authority against allied trade practices, not a novel escalation in isolation.
