The nomination of Debevoise & Plimpton partner Mary Jo White as the next chairman of the U.S. Securities and Exchange Commission means that the agency will continue with an aggressive approach to Wall Street enforcement, financial regulation attorneys say.

White has a reputation for being smart, fair and, most importantly, a tough enforcer. As the first female U.S. attorney for the Southern District of New York, she became known for taking down white-collar criminals, crime syndicate boss John Gotti and terrorists.
