The head of the New York attorney general’s investor protection bureau Katherine Milgram is leaving to take a position as head of regulatory affairs and chief of staff to the chief legal counsel at Guardian Life Insurance Co., according to the AG’s office.

Milgram, who has been the head of the bureau since February 2016, will be succeeded by chief of the enforcement section, Cynthia Hanawalt, according to the AG’s Office. The bureau is responsible for enforcement under New York’s Martin Act, the powerful securities anti-fraud law that gives the AG’s Office broad law enforcement powers.
