Update, 2/7/13, 1:30 p.m. EST: This story has been revised to include a statement from Greenberg Traurig responding to the assertion that the management changes announced Wednesday were being made without a partnership vote.

In a management shuffle announced Wednesday, Greenberg Traurig has promoted Miami shareholder Hilarie Bass to co-president, making her one of the highest-ranking women at a major U.S. law firm.
