U.S. Senator Elizabeth Warren has not endorsed Bitcoin, despite speculation arising from a flag flown over the U.S. Capitol supposedly in honour of Bitcoin's creator, Satoshi Nakamoto. Known for her critical stance on blockchain and Bitcoin, Warren's office clarified that the flag was raised through a routine process where anyone can submit a request, rather than being a special endorsement from Warren. The incident was viewed as a clever stunt by Bitcoin supporters, with Warren's office adopting a free-speech approach to moderating submissions to its flag request form. Bitcoin Magazine, which initially reported on the incident, has not commented on the matter.
