In November 2010, the State Duma (lower house of the Russian parliament) passed a resolution declaring long-classified documents "showed that the Katyn crime was carried out on direct orders of Stalin and other Soviet officials". The declaration also called for the massacre to be investigated further to confirm the list of victims. Members of the Duma from the Communist Party denied the Soviet Union had been to blame for the Katyn massacre and voted against the declaration. On 6 December 2010, Russian President Dmitry Medvedev expressed commitment to uncovering the whole truth about the massacre, stating "Russia has recently taken a number of unprecedented steps towards clearing up the legacy of the past. We will continue in this direction".
