Elizabeth Warren

From her wiki:

For 10 years, she was chair of the litigation department at Debevoise & Plimpton.[8]* The Huffington Post called her "a well-respected attorney who won high-profile cases against mobsters, terrorists and financial fraudsters over the course of nearly a decade as the U.S. attorney for Manhattan."[9]

It has been asserted in Rolling Stone magazine that, among other duties at Debevoise, White has used her influence and connections to protect certain Wall Street CEOs from prosecution,[10] including a notable case involving the firing of Gary J. Aguirre for investigations into the CEO of Morgan Stanley executive John J. Mack.

In 2013, she was involved in the prosecution of Aaron Swartz as lawyer for JSTOR, where she asked the lead prosecutor to drop the charges.[11]

When White started at the SEC in April 2013, most of the agency's enforcement cases from the 2008-2009 financial crisis were either settled or near completion, freeing up resources for other work.[12] In a shift for the agency, White announced in June 2013 the SEC would start demanding more admissions of misconduct as part of an enforcement settlement.[13] In an October 2013 speech, White announced a new SEC enforcement tactic practiced by neighborhood beat police to root out crime. In her speech, White cited a March 1982 Atlantic article that theorized enforcing small, petty crimes - like smashed windows - can prevent bigger crimes. Focusing enforcement attention to these small crimes avoids breeding an environment of indifference to the rules, White said. During her tenure, White has had to recuse herself from some of the SEC's biggest enforcement cases as a result of her prior work at Debevoise and her husband, John W. White, a lawyer at Cravath, Swaine & Moore.*[14]
