New York's head financial services regulator wants Congress to look at her state's rules around crypto when thinking about a national model and warned against federal laws overriding state regimes. 

“When we go to the Hill, we say we want there to be a state path,” said Adrienne Harris, the New York Department of Financial Service’s superintendent. “We would like for there to be a framework nationally that looks like what New York has, because I think it is proving itself to be a very robust and sustainable regime.”

Harris particularly noted concerns that federal legislation could preempt, or override state regulatory regimes during her appearance today at the Brookings Institution in Washington, D.C.
