Joe Biden became a U.S. Senator when he was 29 and served two terms as Vice President in the Obama administration. He’s always been known as a regular guy, someone who can relate to the postal worker and the secretary. He’s also experienced tragedy. Four years ago, Biden’s oldest son Beau died of brain cancer. In this episode of “Now What?” host Carole Zimmer talks to the Vice President and Dr. Jill Biden about cancer, loss, hope and whether he will make that much talked about run for the Presidency. Now What?” was produced with help from Jackson Bierfeldt, Steve Zimmer and Gabe Zimmer. Audio production is by Nick Ciavatta.
