Greenspan to testify

He’ll be followed a day later by two former Citigroup chairmen; Bob Rubin, who headed the Treasury Department during the Clinton administration; and Chuck Prince.

Greenspan and Rubin held their posts during a huge expansion of the U.S. economy, but have since become targets of the left.

Rubin pushed for de-regulating the financial sector, something liberals believe led to the financial crisis. Greenspan has come under criticism for not seeing the housing bubble or the development of lending practices threatening to the underlying economy.
