I want to know the answer to the following question:
When did Lehman's former CEO appear before Representative Henry A. Waxman?
All the background I'm provided with is that "On Oct. 6, 2008, three weeks after Lehman Brothers filed the largest bankruptcy in U.S. history, Lehman's former CEO found himself before Representative Henry A. Waxman, the California Democrat who chaired the House Committee on Oversight and Government Reform.". Is that enough to answer the question?
