Bitmain Security Concerns! Warren Sends Letter to the Commerce Department, Inquiring About the Truth of Trump's Family Purchases.

Senator Elizabeth Warren sent a letter to the Department of Commerce on March 26, requesting documentation related to Bitcoin mining hardware manufacturer Bitmain. The Trump family’s American Bitcoin had procured 16,000 mining machines from Bitmain, raising Warren’s concerns about potential impacts on national security decisions.

“Operation Red Sunset”: The Full Background of the National Security Investigation Into Bitmain

The context of Warren’s letter is the ongoing security reviews by the U.S. government concerning Bitmain. In November 2025, Bloomberg first reported on “Operation Red Sunset,” led by the Department of Homeland Security, where investigators are examining whether Bitmain’s ASIC chips could be remotely controlled for espionage or to disrupt the U.S. power grid. This investigation was initiated during the Biden administration and continued into the early days of the Trump administration.

Core Allegations of the Investigation and Positions of Various Parties

Department of Homeland Security Investigation: Reviewing whether Bitmain’s ASIC chips have vulnerabilities that could allow for remote control

2024 Federal Review: Confirming that Bitmain’s equipment poses “national security risks” near U.S. military bases

Senate Intelligence Committee Report: Pointing out “several concerning vulnerabilities” that could be manipulated by Chinese entities

Bitmain’s Position: Completely denying the allegations, claiming “strict compliance with U.S. laws and regulations, and has never engaged in activities that pose risks to U.S. national security”

Trump Family Procurement Transaction: The Core of Warren’s Conflict of Interest Concerns

According to SEC documents cited by Bloomberg, American Bitcoin, co-founded by Eric Trump and Donald Trump Jr. in partnership with the established miner Hut 8, spent $314 million in August 2025 to purchase 16,000 Bitmain mining machines.

Since then, American Bitcoin has continued to expand its hashing power: earlier this month, it announced the addition of 11,298 ASIC miners, bringing its total holdings to approximately 89,242 machines, with a hashing power of about 28.1 EH/s. The company’s Bitcoin reserves have increased to approximately 6,900 coins, valued at around $462 million based on current market prices.

In her letter, Warren requested that the Department of Commerce explain what measures have been taken to “protect the national security decisions of the Department of Commerce from being influenced by companies with business ties to the Trump family,” stating that “cryptocurrency interest groups with close political relationships must not receive special treatment that could jeopardize national security.”

This is part of Warren’s series of investigations into potential conflicts of interest surrounding the Trump administration’s cryptocurrency policies. She has previously written to cryptocurrency affairs head David Sacks, demanding financial disclosures before the White House cryptocurrency summit and pressuring the Treasury Department regarding potential loopholes in the “GENIUS Stablecoin Act.” Currently, the Democratic Party holds a minority in the Senate and lacks the legislative power to compel a response from the Department of Commerce; as of the time of publication, the Department of Commerce has not responded to requests for comment.

Frequently Asked Questions

Why is Bitmain considered a national security risk for the United States?

Multiple U.S. government reports indicate that Bitmain’s ASIC chip technology may have vulnerabilities that could allow for remote control, and some of the equipment has been deployed near U.S. military bases. Security agencies are concerned that these devices could be exploited by the Chinese government for intelligence gathering or to disrupt critical infrastructure, including power grid systems.

What is the scale of the procurement by American Bitcoin under the Trump family in relation to Bitmain?

American Bitcoin spent $314 million in August 2025 to purchase 16,000 Bitmain mining machines and has continued to expand its procurement, currently holding about 89,242 hashing servers with a power capacity of 28.1 EH/s and Bitcoin reserves of approximately 6,900 coins, valued at around $462 million.

Can Warren’s letter compel the Department of Commerce to respond?

Currently, the Democratic Party holds a minority in the Senate and lacks the legislative authority to compel executive agencies to respond. This letter is a formal request for information, primarily aimed at publicly applying pressure and creating an accountability record, and does not have legally binding power.
