SEN. TIM KAINE:

Hillary Clinton is somebody who has had a passion for families and children since she was a kid, in a Methodist youth group as a teenager in the suburbs of Chicago.

And what I tell people, Gwen, is this. If you want to know about the character of somebody in public life, look to see if they have a passion that has animated them throughout their life, whether they were in office or out, whether they were winning elections or losing them.

And Hillary Clinton has that, a passion to empower families and kids, and a desire to measure health of society by how families and kids are doing. You can see this from her service as a lawyer, first lady of Arkansas, and United States senator, and secretary of state.

And I draw that contrast with a Donald Trump. What's the passion that has animated his life, other than Donald Trump? And there really isn't one. And so that is the important definition, in my view, of character in public life. Can you count on somebody? Do you know what motivates them? And with Hillary Clinton, I think that's very, very plain.
