Robertson will serve as head of the office, a post previously held by Laricke Blanchard, who will stay on at the Fed with his title, assistant to the board of legislative affairs.
Smith would not comment on why the leadership change was made. However, one Bloomberg report suggested that Robertson was brought on to counter skepticism about the Fed's growing role in the nation's financial system.
Previously, Robertson led the office of government, community, and public affairs at John Hopkins University and was VP of government affairs at Enron. She has also served as an adviser to the Clinton administration's Treasury secretaries.
