Legal Ex-SEC enforcement head Alex Oh hires D.C. bar president to battle sanctions motion Caroline Spiezio 3 minute read The Exxon corporate logo is pictured at one of the company's gas stations in Arlington, Virginia, August 10, 2011. REUTERS/Jason Reed Alex Oh, who became head of the U.S. Securities and Exchange Commission's enforcement division last month but resigned a week later, has hired a lawyer of her own in a long-running international human rights case tied to her abrupt departure. Oh resigned from the agency on April 28, after a judge said he was considering sanctions against her in litigation involving Exxon Mobil Corp that she had worked on at Paul, Weiss, Rifkind, Wharton & Garrison. On Thursday Geoffrey Klineberg of Kellogg, Hansen, Todd, Figel & Frederick entered an appearance in the Exxon case to represent Oh "with respect to sanctions issues."
