U.S. Treasury Secretary Timothy Geithner (C) and his wife Carole Sonnenfeld (R) attend the Inaugural Luncheon in Statuary Hall on Inauguration day at the U.S. Capitol. For more Geithner lunch news, read on. - 

Former Treasury secretary Timothy Geithner has a new book out, as you may have heard. 

As part of the publicity campaign, the website Charitybuzz auctioned off lunch with Mr. Geithner today, with proceeds to benefit the RFK Center for Justice and Human Rights.

$50,000 was the winning bid.

Nice and all, but a good deal shy of the 2013 record holder... a $610,000 lunch with Apple CEO Tim Cook.
