The 'existential wound' inspiring Natasha Trethewey's poetry

Natasha Trethewey is a two-time U.S. poet laureate and a winner of the Pulitzer Prize for her collection “Native Guard.” Now, she has written a memoir about her childhood, the murder of her mother and her own career calling. Titled “Memorial Drive,” the book came out Tuesday. Jeffrey Brown has a conversation with Trethewey for our ongoing arts and culture series, Canvas.
