Mary John Miller, an official at the Treasury Department, has declined to be considered as a candidate for the chairmanship of the Securities and Exchange Commission, according to the New York Times. Her exit puts the focus on other executives said to be under consideration in Washington, including Sallie Krawcheck, a former executive at Bank of America and Sanford Bernstein, Richard Ketchum, chairman of the Financial Industry Regulatory Authority, and Robert Khuzami, the SEC's enforcement chief.

After SEC Chairman Mary Schapiro announced Monday that she was stepping down next month, President Obama named SEC Commissioner Elisse Walter to replace her. But Walter's term expires next year and according to the Times, she has said she will only serve “for a short time.”
