Tucker Carlson, the influential broadcaster admired by President Trump

The US commentator Tucker Carlson began his working life as a respected and brilliant writer on a small conservative magazine. He moved to television commentary, then cable television, and now spreads his controversial views far and wide on streaming services. Biographer Jason Zengerle says one of Carlson's great skills is taking the messaging of far right extremists and making it seem more palatable to a wider audience.Guest: Jason Zengerle, writer with the New Yorker.  Author of 'Hated by all the right people: Tucker Carlson and the unravelling of the conservative mind' (Scribe) Producer: Ann Arnold
