Here Come the Democrats? Critical Minerals Policy May Survive a Political Shift-But the Rules Could Change

Highlights

• Democrats have introduced multiple critical-minerals bills targeting domestic mining, processing, magnet production, and allied supply chains—showing bipartisan strategic alignment.
• Congressional scrutiny of federal financing is already sector-wide, with Democratic lawmakers seeking records from MP Materials, Lithium Americas, USA Rare Earth, and others.
• The political fight ahead is less about whether Washington backs critical minerals and more about which companies get support and what oversight conditions apply.
• USA Rare Earth and Cantor Fitzgerald face conflict-of-interest inquiries from Sens. Warren, Wyden, and Van Hollen—allegations only, with no findings of wrongdoing.
• ReElement Technologies and other heartland manufacturers are investing heavily to rebuild U.S. rare earth industrial capacity and need full political-class support.

Here come the Democrats—and the rare earth industry should pay attention. With control of Congress contested in the 2026 midterms, companies should consider what Democratic control of either chamber could mean for critical-minerals policy. One assumption looks increasingly questionable: that Democrats would dismantle America's push to reduce dependence on China.

Democrats have built their own critical-minerals industrial-policy architecture. The objective often looks familiar: mine and process more domestically, recycle more, manufacture magnets in America, build allied supply chains, and reduce strategic dependence on China. What could change is how Washington selects companies, finances projects, and scrutinizes conflicts of interest.

REEx Insight — The Strategy Looks Durable. The Deal Structure May Not Be

The legislation tells the story. Sen. Catherine Cortez Masto (opens in a new tab) introduced the Rare Earth Magnet Security Act (opens in a new tab), creating a proposed tax credit for domestically produced high-performance rare-earth magnets. A couple of years ago, Sens. John Hickenlooper and Chris Coons backed the Critical Materials Future Act (opens in a new tab), which would establish a DOE pilot supporting domestic critical-material processing.

Coons and Hickenlooper also introduced the Senate Finding ORE Act (opens in a new tab), while House Democrats Kathy Castor and Chrissy Houlahan joined its House version. The legislation uses U.S. geological expertise to cooperate with partner countries on mapping critical-mineral and rare-earth deposits.

Rep. Ro Khanna joined Republican China Committee Chairman John Moolenaar on the Magnets Value Chain Support Act, (opens in a new tab) targeting domestic permanent-magnet production and use. Rep. Ami Bera's bipartisan DOMINANCE Act (opens in a new tab), focused on allied critical-mineral investment and supply-chain security, passed the House in June 2026. Sen. Elissa Slotkin's PRIMED Act (opens in a new tab) targets permitting for qualifying domestic mining, processing, and related manufacturing projects, while she separately introduced legislation addressing increased DoD procurement of U.S.-sourced strategic and critical materials.

This is not simply an anti-mining coalition. It demonstrates substantial bipartisan overlap around the strategic objective, even where lawmakers differ over permitting, environmental standards, and federal financing mechanisms.

USA Rare Earth Is Only Part of the Story

USA Rare Earth has attracted additional Democratic scrutiny over its Commerce Department agreement and Cantor Fitzgerald's role in its private financing. In July, Sens. Elizabeth Warren, Ron Wyden, and Chris Van Hollen and Rep. Zoe Lofgren sought documents from USAR and Cantor while raising potential conflict-of-interest questions. Those inquiries are allegations and oversight questions—not findings of wrongdoing.

But USAR is not alone.

In February, Democratic ranking members Jared Huffman, Robert Garcia, and Martin Heinrich opened a broader inquiry seeking records concerning federal equity transactions involving Trilogy Metals, Lithium Americas, MP Materials, Vulcan Elements, ReElement Technologies, Korea Zinc, and USA Rare Earth.

Note that ReElement Technologies has backed away from that initial financing pursuit. And REEx reminds all that companies such as ReElement and others are investing and working furiously to rebuild an industrial base in the heartland of America (in the case of ReElement, Indiana). This is by no means easy and requires full support of the political class.

That is an important signal for investors: congressional scrutiny of critical-minerals financing is already sector-wide.

REEx Connect — Democrats Active in Critical Minerals

The strategic lesson is straightforward. America's critical-minerals buildout increasingly has bipartisan roots. The political battle may be less about whether Washington supports the sector than about which mechanisms it uses, which companies receive support, and what conditions and oversight accompany taxpayer capital.
