White also said in a separate letter to the SEC's ethics officer that she would step aside from all decisions before the SEC brought by her husband's firm, Cravath, Swaine & Moore, which is also based in New York. In addition, her husband will sell his shares in several investment funds.
The SEC chairman and commissioners must vote to approve enforcement actions against companies or individuals. The agency has been criticized in recent years for not bringing charges against top executives of major banks that contributed to the 2008 financial crisis.
White's pledges to recuse herself from decisions affecting former clients or current clients of her husband are in line with federal ethics guidelines for agency officials. In both cases, she said she would step aside unless she gets a specific exemption from the SEC ethics officer.
