Biden and his administration condemned human rights violations by the Russian authorities, calling for the release of detained dissident and anti-corruption activist Alexei Navalny, his wife, and the thousands of Russians who had demonstrated in his support; the U.S. called for the unconditional release of Navalny and the protestors and a credible investigation into Navalny's poisoning. On March 2, 2021, the U.S. and European Union imposed coordinated additional sanctions on Russian officials, as well as the FSB and GRU, over Navalny's poisoning and imprisonment. The State Department also expanded existing sanctions from the Chemical and Biological Weapons Control and Warfare Elimination Act that had been imposed after the poisoning of Skripal. The Biden administration is also planning to impose sanctions against Russia because of the 2020 SolarWinds cyberespionage campaign, which compromised the computer systems of nine federal agencies. Biden's national security adviser Jake Sullivan said the response "will include a mix of tools seen and unseen, and it will not simply be sanctions."
