Diane Rehm's weekday talk show precedes the Exchange, but today (April 4), she's part of it.
2016 is a big year for the longtime radio host; she's announced her retirement later this year, and published a book, On My Own, about her recent widowing.
Her late husband John was fed up with years of suffering with Parkinson's disease, and his struggles turned Diane Rehm into a supporter of the right to die movement, which Oregon pioneered. She visits with a look back at her illustrious career and vignettes from her book.
