President Joe Biden is clamping down on Russia over a host of aggressive acts, marking a pivot from former President Donald Trump‘s sometimes light approach to the U.S. adversary and its president, Vladimir Putin.

Biden announced long-awaited sanctions Thursday morning, citing Russia‘s efforts to undermine U.S. elections and launch cyberattacks against the U.S. government and businesses, as well as its treatment of dissidents and journalists, such as Russian opposition leader Alexei Navalny.
