Key players in the health care hearings —
Rep. Darrell Issa, R-California, is the chairman of the House Government Oversight Committee. On October 31, Issa's committee issued a document subpoena to Health and Human Services Secretary Kathleen Sebelius for documents and information related to HealthCare.gov. "I've lost my patience," Issa said to CNN's Wolf Blitzer in explaining the decision to use a subpoena. Issa also said his committee has sent a document subpoena to website contractor Optum/QSSI.
