"I remember his eyes. I wish I didn’t," Valerie Biden Owens writes in a new memoir, "Growing Up Biden," describing the moment when her brother — Joe Biden, barely 30 and just elected to the U.S. Senate — understood that his wife and baby daughter had been killed in a car accident.
Why it matters: No one knows President Biden better than his sister, his closest lifelong confidant, supporter and adviser. Her book, out Tuesday, is her story — but it's chockablock with new insights about her big brother.
