What's the latest in the Alexei Navalny poisoning case?

The Kremlin critic released a 49-minute audio confession Monday from a man allegedly behind his near-fatal Novichok poisoning, after Navalny phoned the man, posing as an intelligence official. The confession adds to independent investigation that last week detailed a state-run operation to try to kill the opposition leader. Navalny fell ill on a plane from Siberia to Moscow in August and was in a coma for weeks. The man told Navalny the poison was applied to the inside of his underpants.
