In February, Alexei Navalny died in a Russian prison camp. Navalny was Vladimir Putin's most prominent critic, an anti-corruption crusader who became a political threat to Putin's nearly quarter-century rule. Shepherded by his wife, Yulia, Navalny's memoir is being published posthumously. Amna Nawaz met with Yulia Navalnaya to discuss her husband's life and his work for his memoir, "Patriot."
