The Securities and Exchange Commission (SEC) is pushing back against Coinbase's subpoena requests for documents related to SEC Chair Gary Gensler. Coinbase is seeking to obtain Gensler's personal email and other documents from his pre-SEC days to challenge the SEC's regulatory stance on digital assets. The SEC has described these requests as 'breathtakingly broad' and a 'blatant impropriety.' This legal battle marks a significant clash between the SEC and one of the leading cryptocurrency exchanges in the United States.
