WASHINGTON: Some of Treasury Secretary Timothy Geithner's closest aides, none of whom faced Senate confirmation, earned millions of dollars a year working for Goldman Sachs Group Inc, Citigroup Inc and other Wall Street firms, according to financial disclosure forms.

The advisors include Gene Sperling, who last year took in $887,727 from Goldman Sachs and $158,000 for speeches mostly to financial companies, including the firm run by accused Ponzi scheme mastermind R. Allen Stanford. Another top aide, Lee Sachs, reported more than $3 million in salary and partnership income from Mariner Investment Group, a New York hedge fund.

As part of Geithner's kitchen cabinet, Sperling and Sachs wield influence behind the scenes at the Treasury Department, where they help oversee the $700 billion banking rescue and craft executive pay rules and the revamp of financial regulations. Yet they haven't faced the public scrutiny given to Senate-confirmed appointees, nor are they compelled to testify in Congress to defend or explain the Treasury's policies.
