'Unfinished business' in racial equity -Harris

"When we look again at how far we have to go, we have a lot of work to do. And by Joe asking me to be his running mate, he has pushed forward something that might have otherwise taken decades," Harris said.

Harris is the first Black woman on a major-party U.S. presidential ticket. The 55-year-old U.S. senator from California, who made her own run for the White House, is also the first Asian-American on a major presidential ticket. Her parents were immigrants, her mother from India and her father from Jamaica.

Harris made the comments in an interview from Biden's home state of Delaware with Errin Haines, editor-at-large for the the 19th*, a nonprofit news organization hosting a summit marking the 100th anniversary of the passage of the 19th Amendment which gave women the right to vote.
