When former Paul, Weiss, Rifkind, Wharton & Garrison partner Alex Oh abruptly left the Security and Exchange Commission last week, just days after joining to head the agency’s enforcement division, it sent the legal community abuzz with questions about what happened.

A recent order from a federal judge raising sanctions in litigation where Oh played a leading role was immediately offered up as a possible explanation. Some progressives cheered her exit, regardless of the cause. And Paul Weiss threw its support behind Oh, with chairman Brad Karp calling her “a person of the utmost integrity and a consummate professional, with a strong ethical code.”
