U.S. lawmakers are escalating scrutiny over cryptocurrency mining supply chains, with Senator Elizabeth Warren (D-MA) firing a letter to Commerce Secretary Howard Lutnick on March 26, 2026. The letter, made public by the Senate Banking Committee on March 30, requests a full review of Bitmain, the Chinese bitcoin mining hardware giant, and its financial and operational links to Eric Trump’s mining venture, American Bitcoin.
Warren Targets Bitmain-Trump Nexus
Warren highlighted that Bitmain, facing potential federal investigations, reportedly sought an “alliance with one of President Donald Trump’s sons”—specifically Eric Trump, co-founder of American Bitcoin. She quoted American Bitcoin CEO Michael Ho, who stated in a recent interview while sitting next to Eric Trump that Bitmain has been “a leading manufacturer for us.” The letter also flags concerns about remote access capabilities of the hardware and its possible weaponization against the U.S. power grid.
Unusual Financing Deals Exposed
Warren asserted that Bitmain provided “extraordinary” terms to Eric Trump’s company: exchanging hundreds of millions of dollars worth of mining equipment for future, “promised” bitcoin instead of cash. Industry experts called the deal “blatantly one-sided in favor of American Bitcoin.” Past federal action against Bitmain affiliate Sophgo Technologies Ltd.—blacklisted for aiding China's advanced semiconductor ambitions—adds to the national security narrative. The letter demands all relevant documents and responses by April 9, 2026.
Industry Pushback and Policy Debate
Pro-Trump industry figures and Commerce Department advisors argue that concentrating hashrate within the U.S. strengthens national security. American Bitcoin executives defend Bitmain as a standard supplier, while mining trade groups deny that hardware can disrupt power systems, citing demand-response mechanisms. The debate underscores a broader policy divide between expanding domestic mining capacity and mitigating foreign dependency risks.
Eric Trump Reiterates $1 Million Bitcoin Prediction
In a separate CNBC interview on February 18, 2026, Eric Trump doubled down on his bullish stance: “I have never been more bullish.” He reaffirmed his prediction that bitcoin will reach $1 million per coin. The timing of this optimism contrasts sharply with the regulatory storm swirling around his business partner.
