US Treasury official says crypto mixers are a ‘concern’ in enforcing sanctions By Cointelegraph

Elizabeth Rosenberg, the assistant secretary for terrorist financing and financial crimes at the United States Department of the Treasury, suggested sanctioning cryptocurrency mixers could help strengthen the government’s response to foreign entities looking to use digital assets for illicit means.

In a Tuesday hearing of the Senate Banking Committee, which covered sanctions on Russia, Rosenberg said having the Treasury Department add crypto mixers like Blender.io or Tornado Cash to its list of Specially Designated Nationals could be an effective way of signaling the U.S. government was acting to prevent entities from circumventing sanctions.
