Richard Fuld, the former CEO of the financial firm Lehman Brothers, during hearings on the bankruptcy filing by Lehman Brothers and bailout of AIG before the House Committee on Oversight and Government Reform alleged that a host of factors including a crisis of confidence and naked short selling attacks followed by false rumors contributed to the collapse of both Bear Stearns and Lehman Brothers. Fuld had been obsessed with short sellers and had even demoted those Lehman executives that dealt with them; he claimed that the short sellers and the rumour mongers had brought down Lehman, although he had no evidence of it. Upon the examination of the issue of whether "naked short selling" was in any way a cause of the collapse of Bear Stearns or Lehman, securities experts reached the conclusion that the alleged "naked short sales" occurred after the collapse and therefore played no role in it. House committee Chairman Henry Waxman said the committee received thousands of pages of internal documents from Lehman and these documents portray a company in which there was "no accountability for failure". In July 2008, U.S. Securities and Exchange Commission chairman Christopher Cox said there was no "unbridled naked short selling in financial issues".
