Two Senate Democrats urge the U.S. Treasury Department to halt production of a commemorative 24-karat gold coin featuring President Donald Trump’s image as part of celebrations for the United States’ 250th birthday. Elizabeth Warren (D-Mass.) and Ron Wyden (D-Ore.) write to officials at the U.S. Mint, arguing that the gold used for the coin could be linked to foreign cartel-controlled mining operations. They contend that tracing the metal’s source raises concerns about whether the U.S. government is inadvertently supporting illicit or illegal activities through procurement for a government-issued product.

The lawmakers’ request focuses on stopping further minting of the Trump-imaged coin rather than pursuing other changes to the broader anniversary program. The outlets report that the senators are calling for the Treasury Department and the U.S. Mint to review or pause production in response to sourcing risks they identify. The move reflects a broader use of congressional oversight to scrutinize how government purchases and commemorative materials are sourced and verified.
