The U.S. Senate Committee on Banking, Housing and Urban Affairs published letters from Ranking Member Elizabeth Warren seeking information from the Department of Commerce, Department of Defense, Export-Import Bank of the United States and U.S. International Development Finance Corporation about potential conflicts of interest linked to a reported Trump family-backed mining venture in Kazakhstan. The letters focus on whether federal agencies are assessing and managing risks arising from the Trump family’s reported financial stake in a company that could receive substantial U.S. government support, and they renew scrutiny of EXIM as Congress works on reauthorizing the bank’s charter this year. According to the committee release, the reported project could seek nearly USD 2 billion in total federal support, including an EXIM letter of interest for up to USD 900 million. Warren’s letters cite reports that a Trump family-linked firm agreed to merge with a critical minerals group holding significant mining rights in Kazakhstan and that the project was described as involving the largest known undeveloped tungsten resource in the world. In a separate letter to EXIM President and Chairman John Jovanovic, she also said the bank had not yet provided revised answers to questions for the record first posed in March 2026 on EXIM operations, corruption risks and conflicts of interest. Warren asked Jovanovic to revise and resubmit his responses by July 10, 2026, and requested that the agency heads answer her conflict-of-interest questions by July 21, 2026.
