The Biden administration unveiled sanctions Tuesday against seven senior Russian officials over the poisoning and detention of Alexei Navalny, the most prominent critic of Russian President Vladimir Putin. 

The sanctions, which were coordinated with similar actions from the European Union against Russian officials, mark the Biden administration's first such action against Moscow. The move also represents a departure from former President Donald Trump, whose administration barely acknowledged the poisoning of Navalny and did not impose any penalties over it.
