This is Jane Pauli. Former First Lady Jill Biden is looking back at a tumultuous four years in the White House.

She talks about her new memoir with Sunday morning correspondent Rita Braver.

You say in the very first chapter, the time to discuss those four years in the White House

so much that I've avoided letting myself think about is now.

What do you mean by that?

Well, I think maybe some of the challenges that I, that, you know, Joe and I faced. And, you know, it goes so fast, Rita. I mean,

those four years just move so fast. We did so much and I'm proud of, so proud of what our

administration accomplished. And so it was kind of after I got out of the White House,

it was a little more time to breathe and tell this story, tell my story of how I felt about

being there.

The opening line of the book is,

once you lose a child, nothing can hurt you.

So what about that?

So I think after we lost Bo, I felt really more resilient.

I think having been through that, you know, the pain and the loss, I think, I don't know.

You just feel like if you can survive the loss of your child, nothing hurts

worse than that.

And of course, you and President Biden just managed to go on with your lives.

And he even said that Bo was the reason that he went for President in the first place.

Yeah. So Bo always and all our children did actually encourage Joe to run.

And, you know, they just had such a beautiful close relationship.

You know, Bo was in politics himself. He was Attorney General, so they had so much in common.
