On March 30, 2026, the U.S. Senate Committee on Banking, Housing, and Urban Affairs disclosed that Senator Elizabeth Warren had sent a letter on March 26 to Commerce Secretary Howard Lutnick, demanding enhanced oversight of Chinese Bitcoin mining hardware manufacturer Bitmain and its ties to Eric Trump’s cryptocurrency mining company, American Bitcoin. The letter highlights potential national security vulnerabilities stemming from foreign-controlled mining equipment deployed across the United States.
Warren Alleges ‘Unusually Generous’ Deal to Secure Political Protection
Warren’s letter contends that Bitmain, facing possible federal investigations, has strategically aligned itself with President Donald Trump’s son, Eric Trump, who co-founded American Bitcoin. In a recent interview, American Bitcoin CEO Michael Ho, sitting alongside Eric Trump, confirmed that Bitmain has been a “leading supplier” for the company. Warren specifically flagged the financing structure: Bitmain provided hardware valued at hundreds of millions of dollars in exchange for future, “promised” Bitcoin rather than cash—a deal industry experts have described as “blatantly generous” in favor of American Bitcoin.
The senator noted that Bitmain-affiliated company Sophgo Technologies Ltd. was previously blacklisted by the Commerce Department for supporting China’s advanced semiconductor ambitions. Bitmain commands a dominant share of global ASIC mining hardware production and has been linked in past reports to Chinese state interests. Warren questioned whether such equipment could be remotely accessed or manipulated to disrupt U.S. power grids, raising concerns about supply chain integrity and foreign influence.
Industry Pushback: National Security vs. Business as Usual
Industry insiders and Trump-aligned officials argue that the scrutiny is a strategic push to domesticate Bitcoin mining hash rate, strengthening national security rather than weakening it. American Bitcoin executives and Commerce leadership have advocated that concentrating mining operations inside the U.S. reduces reliance on foreign infrastructure. Meanwhile, mining advocacy groups reject claims that mining hardware can interfere with grid systems, noting that facilities often participate in demand-response programs, voluntarily reducing power usage during peak periods.
The letter demands that Secretary Lutnick provide documents and responses by April 9, 2026, warning that “national security decisions about export controls and U.S. trade regulations must be free from improper political influence.” The Commerce Department holds statutory authority over export controls and communications technology risk management, placing it at the center of the controversy.
Eric Trump Reiterates Bitcoin $1 Million Prediction
Separately, Eric Trump has reaffirmed his prediction that Bitcoin will reach $1 million per coin. Speaking to CNBC on February 18, 2026, he stated: “I’ve never been more bullish.” Whether Warren’s pressure campaign will alter the Trump family’s entanglement with the crypto mining industry remains an open question as the deadline for Commerce Department’s response approaches.
