John James, House Representative of Michigan, announced that his legislation aimed at enhancing U.S. control over critical minerals and fortifying supply chains has progressed in committee. The announcement was made on the social media platform X.
“Big win for American security,” said James. “My bill to secure our critical mineral supply just passed the Energy & Commerce Committee. From smartphones to fighter jets, these minerals power our daily lives and our national defense—but China controls over 80% of global refining. This bill brings that control back home, protecting jobs, strengthening supply chains, and keeping America in the lead.”
U.S. policymakers have intensified efforts in 2025 to secure critical mineral supply chains and reduce reliance on China. According to AP News, this includes the launch of the Quad Critical Minerals Initiative and the introduction of federal legislation such as the Intergovernmental Critical Minerals Taskforce Act. These initiatives aim to diversify sources for minerals crucial to defense and technology while bolstering domestic resilience.
According to the U.S. Geological Survey and Government Accountability Office (GAO), the United States imports more than 90% of its rare earth minerals and significant portions of other critical elements like titanium, tungsten, and tantalum, which are vital for military and technology sectors. The Department of Defense is actively stockpiling materials and developing new recovery methods to mitigate risks associated with dependence on China.
Wikipedia notes that China controls approximately 60–70% of global rare-earth mining and about 90% of refining capacity, whereas the U.S. operates just one rare-earth mine at Mountain Pass, producing around 15.8% of global output. This disparity underscores the urgent need for increased U.S. refining and processing capacity.
James is a Michigan Republican and former U.S. Army captain who previously served as a state senator before becoming a member of Congress. Public records and media profiles indicate that he has concentrated on national security, veteran affairs, and manufacturing, advocating for bipartisan policies to strengthen critical mineral supply chains and enhance U.S. industrial capacity.
