Citigroup top executive
His nameplate is gone from the office of the Treasury Secretary, but in some respects, Rubin, 63, never really left. Now a top executive at Citigroup, the man who steered President Clinton through financial crises to the nation's longest boom gets invited to private meetings of top congressional leaders from which the current Treasury Secretary is excluded. Since Sept. 11, Rubin has helped Congress shape a stimulus package. He even testified alongside Alan Greenspan when the Fed chief delivered his damage assessment to a closed session of the Finance Committee.
