Two powerful House Democrats have sent a letter to insurance companies asking them to provide detailed information about their conferences and retreats, executive pay, and other business practices. The letter is from Rep. Henry Waxman (D., CA), who is chairman of the House Energy and Commerce Committee, and Rep. Bart Stupak (D., MI), who heads the panel's Subcommittee on Oversight and Investigations. The letter did not refer to the health overhaul debate, saying only that the committee "is examining executive compensation and other business practices in the health insurance industry."
