The United States Department of Justice is expected to announce a “major international cryptocurrency enforcement action.”

According to a Jan. 18 announcement, U.S. Deputy Attorney General Lisa Monaco will lead a press conference in which the Justice Department will announce a major enforcement action — now believed to be against the crypto firm Bitzlato. The U.S. Treasury Department is also expected to announce a similar enforcement action.

Other speakers at the event will include Assistant Attorney General Kenneth Polite of the Department of Justice’s criminal division, U.S. Attorney Breon Peace of the Eastern District of New York, FBI Associate Deputy Director Brian Turner, and Deputy Treasury Secretary Wally Adeyemo.
