A federal court judge has called on cryptocurrency exchange Coinbase to abandon or significantly alter its efforts to obtain the private communications of Securities and Exchange Commission (SEC) Chairman Gary Gensler. Judge Katherine Polk Failla expressed surprise at Coinbase's request and pointed out its inappropriateness. However, she asked the exchange to submit a reasoned application for formal consideration of the issue. Coinbase wanted to obtain Gensler's documents prior to his appointment as chairman of the regulator.
