In May 2005, the subcommittee held the hearings on their investigation of abuses of the program, including oil smuggling, illegal kickbacks and use of surcharges, and Saddam Hussein's use of oil vouchers for the purpose of buying influence abroad. These hearings covered certain corporations and several well-known political figures, including Russia's Vladimir Zhirinovsky and drew significant media attention for the combative appearance of British politician George Galloway, an anti-Iraq-War member of parliament for RESPECT The Unity Coalition (Respect), who vigorously denied the subcommittee's allegations against him and claimed they were politically motivated.
