California Attorney General Xavier Becerra lashed out at lawmakers for imposing “unworkable obligations and serious operational challenges” on his office by effectively making him the chief enforcer of the state’s sweeping new data privacy law.

In an Aug. 22 letter to legislators who helped get the law passed in June, Becerra complained that his office is not equipped to handle all the related duties, including quickly drafting regulations and advising businesses about compliance with the California Consumer Privacy Act, or CCPA.
