Coinbase co-founder and CEO Brian Armstrong has supported multiple Republican candidates in the upcoming U.S. Senate elections in November. Lawyer John Deaton and former Bridgewater CEO David McCormick are running as Republicans, with Deaton contesting a Senate seat in Massachusetts and McCormick contesting a Senate seat in Pennsylvania. In another X post on October 20, the Coinbase CEO also backed Republican challenger Deaton, who is attempting to unseat Democratic Senator Elizabeth Warren, known for her skeptical stance on cryptocurrencies. While Armstrong supports Republican Senate candidates, he has not endorsed any presidential candidates.
