SOME DOUBTS on Geithner in the New York Times, no less:

"We have only two things to say about Tim Geithner, who we do not know: AIG and Lehman Brothers," said Christopher Whalen of Institutional Risk Analytics. "Throw in the Bear Stearns/Maiden Lane fiasco for good measure," he said, referring to the site of the New York Federal Reserve, where many rescue discussions took place.

"All of these 'rescues' are a disaster for the taxpayer, for the financial markets and also for the Federal Reserve System as an organization. Geithner, in our view, deserves retirement, not promotion."

Ouch.

"He was in the room at every turn of the crisis," said another executive who participated in several such confidential meetings with Geithner. "You can look at that both ways."

While Henry Paulson Jr., the current Treasury secretary, has taken a drubbing for the changeable nature of the government's efforts to bolster the financial industry — some of which clearly contradicted each other — Geithner has managed, for the most part, to remain unscathed. He's been widely praised as a bright, articulate out-of-the box thinker who is a bailout expert, to the extent anyone can truly be an expert at fast-changing emergencies.

Behind the scenes, Geithner was the point person for weeks of sleep-deprived Bailout Weekends. It was Geithner, not Paulson, for example, who put together the original rescue plan for the American International Group.

And, of course, Geithner also oversaw and regulated an entire industry whose decline has delivered a further blow to an already weakened American economy. Under his watch, some of the biggest institutions that were the responsibility of the New York Fed — Bear Stearns, Lehman Brothers, Merrill Lynch and most recently, Citigroup — faltered. While he was one of the first regulators to smartly articulate the potential for an impending disaster, a number of observers question whether he went far enough to stop the calamity.

Perhaps what has most people on Wall Street stirring is Geithner's role in the fall of Lehman. At the time of its bankruptcy, he, along with Paulson, appeared to be the most vocal in supporting the government's refusal to bail out the firm, according to people involved in various meetings. With hindsight, many in the financial industry blame a deepening of the global financial crisis on the government's decision to let Lehman crumble.
