The US Department of Justice (DOJ) opposes the motion to dismiss the charges of conspiracy and money laundering against Tornado Cash co-founder Roman Semenov. They believe that the defense has raised disputed facts that should be considered by a jury and not dealt with at an early stage. The DOJ accuses Semenov and others of conspiring to launder money, operating an unlicensed money transmitting business, and violating sanctions, alleging that entities such as North Korea's Lazarus Group used Tornado Cash for money laundering.
