Kamala Harris made a career of straddling issues and rebranding herself while moving from prosecutor and legislator. Now the presumptive U.S. vice presidential nominee will have to rebound from her hard-nosed law enforcement record to become an agent of change in the age of racial justice protests.

At 55, Harris brings to the Biden campaign relative youth, deep electoral experience and a reputation for sharply challenging Republican appointees such as Supreme Court Justice Brett Kavanaugh and Attorney General William Barr. She's also the first Black woman and first Asian American woman to compete on a major U.S. party’s presidential ticket.

She is expected to keep up attacks on President Donald Trump and Vice President Mike Pence, just as she has for months as the front-runner to be Biden’s running mate.
