Ripple CEO Brad Garlinghouse expressed strong disapproval towards US Securities and Exchange Commission Chairman Gary Gensler on Tuesday, labeling the SEC chief as a “political liability” in light of an ongoing legal battle.

The cryptocurrency company is contesting SEC accusations that it and its executives engaged in unlawful sales of XRP tokens as unregistered securities. Notably, a case against Garlinghouse and his colleague Chris Larsen was dismissed in October.
