U.S. President Joe Biden met with Russian opposition figure Vladimir Kara-Murza and his family in the White House on August 15. Kara-Murza was released from a Russian prison as part of a large prisoner swap between Moscow and several Western countries on August 1. Biden posted on Facebook that the meeting was held "to celebrate his return to America" after being "unjustly imprisoned in Russia for speaking out against Russia's war in Ukraine." Kara-Murza, who was the target of two poisoning incidents that he blames on the Russian government, was serving a 25-year sentence on a treason conviction.
