The European Commission has said it will ban “the Kremlin’s media machine” in the EU. RT, Sputnik and other outlets “will no longer be able to spread their lies to justify Putin’s war,” European Commission President Ursula von der Leyen tweeted.

Several companies, including Google, TikTok, Facebook and Microsoft, are already carrying out that ban and are restricting access to Russian state-owned media within the EU.

The U.K.’s media regulator, Ofcom, said Monday it’s launching 15 investigations into RT, Russia’s state-backed television channel.

A group of leading Ukrainian media groups wrote an open letter to global TV providers urging them to stop distributing Russian state networks.

What we’re watching: Crackdowns from private companies, including Big Tech platforms, may prove even more potent, given how much Russian state media has relied on social networks to spread disinformation.
