Sen. Elizabeth Warren requested Commerce Department records related to Bitmain, seeking information about potential national security risks tied to the company’s ASIC Bitcoin miners. The existing topic record cites a reported November 2024 Department of Homeland Security probe called "Operation Red Sunset" and asks for details on communications involving Bitmain, Commerce officials, and the Trump family. The new update adds that Warren asked Commerce for Bitmain records while federal review of mining hardware and security concerns remains ongoing. The report also notes that American Bitcoin Corp. previously bought 16,000 Bitmain mining machines for $314 million.
