In late April 2015 Vladimir V. Kara-Murza and Mikhail Kasyanov presented a list of eight names to members of the House of Representatives and the Senate of the US Congress.
Kara-Murza explained the appeal to US legislators by saying that Russia's law-enforcement agencies, unfortunately, had declined to investigate these recorded and documented statements although incitement to harm an individual was also a crime according to the Criminal Code of the Russian Federation.
