EU tech regulators stress test Twitter's content moderation ahead of new rules.

European Union Commissioner Thierry Breton conducted a "stress test" at Twitter's San Francisco headquarters to analyze how the company responds to tweets that European regulators deem problematic. Breton's trip to the West Coast reflects the rapid expansion of the European Union's influence, as it advances a robust artificial intelligence bill and prepares to enforce the Digital Services Act and the Digital Markets Act, a pair of laws that could have far-reaching consequences for the future of the internet. The European Union's activity stands in stark contrast to the United States, where efforts to pass new laws governing tech platforms have often fallen behind other priorities.
