The timing—with Musk's summons arriving days after the DOJ's rebuff—underscores the stakes of cross-border enforcement actions against major platforms. Attorneys representing X or its executives should monitor whether France pursues enforcement unilaterally and whether the DOJ's position reflects broader U.S. policy on First Amendment protections for algorithmic speech and AI-generated content in international contexts.
