Gemini co-founders and cryptocurrency advocates Tyler and Cameron Winklevoss announced Thursday that they have each donated $500,000 in Bitcoin to help unseat Senator Elizabeth Warren in the November U.S. Senate election.

The Winklevoss brothers have reportedly spoken out against Warren several times before, calling the senior Massachusetts senator "one of the greatest threats to American prosperity." Tyler Winklevoss said on the X platform on Thursday: "She is public enemy number one when it comes to cryptocurrency. She is the primary architect and promoter of the Biden administration's war on cryptocurrency."
