Mary Jo White has been sworn in as the 31st chair of the Securities and Exchange Commission, the SEC announced Wednesday. White, a former U.S. prosecutor known for tackling complicated fraud cases, was confirmed by the Senate Monday after the president nominated her to the post on Feb. 7. "It is an honor to lead the talented and dedicated SEC staff on behalf of America's investors and markets," said White. "Our markets are the envy of the world precisely because of the SEC's work effectively regulating the markets, requiring comprehensive disclosure, and vigorously enforcing the securities laws." She will replace Elisse Walter, who has served as SEC chairman since Mary Schapiro left the commission last December. Walter is expected to remain an SEC commissioner through this year.
