Reaction to Navalny's death: Biden calls for the hunt for Putin's oligarchs. The United States has imposed economic sanctions on the Russian economy for about two years because of the war in Ukraine.

Some experts predicted that tough U.S. sanctions on Russian oligarchs would prompt them to turn against Putin. But at least so far those hopes have not been realized.
