Letters: Tim DeChristopher's River Trip

Robert Siegel and Guy Raz read emails from listeners about Alex Chadwick's story on Monday's program. Chadwick, a former NPR colleague, took a trip down the rapids of the Green and Colorado rivers with climate activist Tim DeChristopher. Chadwick was still grieving his late wife while DeChristopher was facing a prison sentence for disrupting an auction of government oil and gas leases. Listeners were moved by Chadwick's story, though some took issue with DeChristopher's attitude about his crime.
