As the question of stablecoin regulation heats up in the US Senate, so has the issue of which members are personally invested in cryptocurrencies and cryptocurrency firms.

On May 19, the Senate voted to invoke cloture and move ahead with the GENIUS Act, which would provide a regulatory framework for stablecoins. The measure passed 66-32, with 16 Democrats supporting the bill.

Democratic concerns over corruption and politicians’ ties to cryptocurrency firms made the bipartisan move controversial. After the vote was finished, Colorado Senator Michael Bennet introduced the STABLE GENIUS Act. The bill would prevent members of Congress from issuing or investing in digital currency and require them to put their crypto in a blind trust while in office.

Bills to prevent members of Congress from investing in companies they regulate have had little success. However, lawmakers are still required to disclose rough estimations of their, their spouse’s and their children’s investments. Here are 11 US senators who have invested in crypto firms.

This list is not exhaustive; there are plenty of companies in which lawmakers invest that are affected by cryptocurrency price movements and market effects. It also does not include any members of the House of Representatives, where crypto regulation is similarly in the works. 

Lawmakers will likely become more interested in investing in crypto as it becomes more mainstream and potential obstacles to congressional investments flounder and fail to move forward.
