From the U.S. Department of the Treasury website:

The Secretary is responsible for formulating and recommending domestic and international financial, economic, and tax policy, participating in the formulation of broad fiscal policies that have general significance for the economy, and managing the public debt. The Secretary oversees the activities of the Department in carrying out its major law enforcement responsibilities; in serving as the financial agent for the United States Government; and in manufacturing coins and currency.
"The Chief Financial Officer of the government, the Secretary serves as Chairman Pro Tempore of the President's Economic Policy Council, Chairman of the Boards and Managing Trustee of the Social Security and Medicare Trust Funds, and as U.S. Governor of the International Monetary Fund, the International Bank for Reconstruction and Development, the Inter-American Development Bank, the Asian Development Bank, and the European Bank for Reconstruction and Development."

AIG bonuses
Although President Obama expressed strong support for Geithner, the outrage over the AIG bonuses has undermined public support. AIG paid bonuses to executives in its Financial Services division after receiving more than $170 billion in federal bailout aid.<44> Even prior to the election, senior aides to Timothy Geithner have closely dealt with American International Group Inc. on compensation issues including bonuses, both from his time as president of the Federal Reserve Bank of New York and as Treasury secretary. In early November, 2008, a committee concluded that the bonuses, which were in contracts signed before the government takeover, couldn't be legally blocked. On March 3, 2009, appearing at a hearing of the House Ways and Means Committee Rep. Joseph Crowley, a New York Democrat, asked him about the bonuses that AIG would be paying to financial-products employees "in the coming weeks." On March 11, Geithner called Mr. Edward Liddy, AIG chief, to protest the bonus payouts. Mr. Geithner and Federal Reserve Chairman Ben Bernanke attended a hearing by Congress on March 24, 2009.<45>
AIG payments to banks
In November 2009, Neil Barofsky, the Treasury Department Inspector General responsible for oversight of TARP funds, issued a report critical of the use of $62.1 billion of government funds to redeem derivative contracts held by several large banks which AIG had insured against losses. The banks received face value for the contracts although their market value at the time was much lower. In the report, Barofsky said the payments "provided with tens of billions of dollars they likely would have not otherwise received". Terms for use of the funds had been negotiated with the New York Federal Reserve Bank while Geithner was president.
In January 2010, Rep. Darrell Issa released a series of e-mails between AIG and the New York Fed. In these e-mails, the Fed urged AIG not to disclose the full details of the payments publicly or in its SEC filings. Issa pushed for an investigation of the matter, and for records and e-mails from the Fed to be subpoenaed. Rep. Edolphus Towns, Chairman of the House Oversight and Government Reform Committee, issued subpoenas for the records and scheduled hearings for late January. Federal Reserve Chairman Ben Bernanke said the Fed would welcome a full review of its actions regarding the AIG payments.<46><47><48><49>
Geithner and his predecessor, former Treasury Secretary Henry Paulson, both appeared before the Committee on January 27. Geithner defended the bailout of AIG and the payments to the banks, while reiterating previous denials of any involvement in efforts to withhold details of the transactions. His testimony was met with skepticism and angry disagreement by House members of both parties.<50><51><52><53>
