Republican Sens. Cynthia Lummis and Bill Cassidy introduced a bill that would bolster digital asset mining as well as codify President Donald Trump's executive order to establish a strategic bitcoin reserve into law. 

The bill, titled the "Mined in America Act," was unveiled Monday and is intended to expand crypto mining’s role in the U.S. economy.

"President Trump pledged to make the United States the digital asset capital of the world, and we’re not backing down," Lummis said in a statement. "The Mined in America Act brings this industry home through forward-thinking initiatives to secure our financial future."

Before being elected president last year, Trump said he planned to make the U.S. "the crypto capital of the planet."

In March, he signed an executive order to create a strategic bitcoin reserve, to be capitalized by bitcoins held by the Department of the Treasury that were forfeited as part of criminal or civil asset seizures. Lummis reintroduced a bill in March, building off that executive order.

The new mining bill would direct the Commerce Department to create a "voluntary certification program" for mining pools and mining facilities and would also require certified facilities to begin a "transition away from mining equipment manufactured by companies tied to foreign adversaries," they said. 

In a post on X, Sen. Cassidy said their bill would support "this key industry."

"Digital asset mining is a big part of our economy," he said. "We should be doing it here in America."

Lummis has been pushing for several different crypto bills, including a broader crypto market structure one, crypto tax reform, and the bill to cement Trump's strategic bitcoin reserve into law. The Wyoming senator announced late last year that she would not be seeking re-election. Her term will end in January 2027.
