Summer Mersinger, a commissioner of the US Commodity Futures Trading Commission (CFTC), said in an interview with CoinDesk that "I think the question of who has the proper authority between the SEC and the CFTC is definitely an issue. In fact, Commissioner Peirce and I will speak together at the Consensus conference. We have some similar views. But this is a struggle because sometimes in the places where we are arguing, whether it is an enforcement case or other actions that we have talked about belonging to our fraud and manipulation enforcement authority, we see the SEC starting to ask questions as if it belongs to their jurisdiction. Therefore, there is definitely some tension here. The main reason for the tension is the lack of clarity."
