May 28 (Reuters) - Democratic U.S. Senator Elizabeth

Warren on Wednesday expressed concern the Trump administration's

tariff negotiations would favor big technology firms at the

expense of consumers and workers.

In a letter to U.S. Trade Representative Jamieson Greer,

Commerce Secretary Howard Lutnick and Treasury Secretary Scott

Bessent, Warren said Big Tech has long sought to use trade

negotiations to "undermine pro-consumer, pro-competition

policies." She asked for details on the officials' interactions

with tech industry executives.

WHY IT'S IMPORTANT

Warren has for years argued in favor of stronger regulation

on big technology firms.

President Donald Trump has taken a stance favorable to the

technology sector, taking aim at foreign governments' regulatory

restrictions and digital services taxes aimed at capturing

revenue from Meta, Apple ( AAPL ), Alphabet's Google,

Amazon ( AMZN ) and other U.S. tech firms.

Trump in February ordered a revival of tariff retaliation

probes over digital services taxes, and Greer and Bessent have

raised U.S. opposition to digital services taxes as part of

trade negotiations.

In her letter, Warren said she was concerned by a list of 10

digital trade grievances against U.S. trading partners posted by

USTR on X, including the European Union's Digital Services Act

and Digital Markets Act and South Korea's cross-border data flow

restrictions.

KEY QUOTE: Warren said that given the industry's large

donations, presence at Trump's inauguration and its success in

lobbying for temporary tariff exemptions, "I am gravely

concerned renegotiated trade deals will be used to advance Big

Tech's anti-consumer agenda while doing nothing to promote U.S.

manufacturing or help American workers."

Spokespersons for USTR, the Treasury and the Commerce

Department did not immediately respond to a request for comment.
