This WSJ editorial says AFL-CIO union leader Trumka's questions about the Lew nomination at Treasury are appropriate even though they come 2 years later. The questions relate to clauses in bank contracts that allow accelerated vesting of equity awards for executives who may be likely to join the government- looking towards favorable treatment of the banks by these executives that join the government. In this case it is Citicorp where Treasury Secretary Lew worked before becoming Treasury Secretary. The original Lew employment contract with Citicorp had a bonus guarantee if Lew left the bank for a "high level position with the United States government or regulatory body." The revolving door has a pernicious effect on America's regulatory system especially for financial markets and bank regulation by permitting behavious that would otherwise be discouraged or penalized.
