Several Democratic lawmakers, including Senators Elizabeth Warren, Richard Blumenthal, and Mazie Hirono, are demanding clarification regarding a reported intervention by a White House official that led to a $620 million loan from the Pentagon to Vulcan Elements, a North Carolina-based startup linked to Donald Trump Jr. The company, which specializes in rare-earth magnets, announced the loan last November, claiming it would enable the production of 10,000 metric tons of magnets annually in the U.S. A recent ProPublica investigation revealed that Trump Jr.'s venture capital firm, 1789 Capital, acquired an undisclosed stake in Vulcan Elements shortly before the loan was finalized. The lawmakers expressed their concerns in a letter to White House Chief of Staff Susie Wiles, emphasizing the need for a fair and unbiased contracting process within the Department of Defense. They argue that the reported actions indicate a troubling level of corruption and influence peddling that could jeopardize national security and misuse taxpayer funds. The lawmakers have requested answers by June 16 and have reached out to the White House for further comments.
