When political and financial commentators refer to the revolving door between Washington and Wall Street, there's no better example than Jack Lew.
The current Treasury Secretary started his government career in the Clinton Administration and later ran Citigroup's Alternative Investments division, a unit that housed many of the firm's risky hedge fund investments and made bets against the housing market.
During his confirmation for Treasury Secretary, lawmakers questioned Lew's 2009 bonus of $900,000 at a time when the bank was receiving billions in taxpayer bailouts.
