The Russian activist Aleksei Navalny has spent years agitating against corruption, and against President Vladimir Putin.

Last summer he was poisoned with a rare nerve agent linked to the Russian state. Last week, after recovering in Germany, he returned to Moscow. He was arrested at the airport, but he managed to put out a call for protest, which was answered in the streets of more than a hundred Russian cities.

Today, we look at the improbable story of Aleksei Navalny.

Guest: Anton Troianovski, who has been a Moscow correspondent for The New York Times since 2019.
