In a one-two upheaval in US politics, President Joe Biden has said he will not run for re-election in November and instead endorsed Vice President Kamala Harris.

Harris already made history by becoming the first Black and female vice president in US history, but has faced concerns over whether she can defeat Republican candidate and former President Donald Trump.

The coming days will show if Harris will indeed be embraced by the party and chosen as their candidate at the Democratic National Convention next month.

On Sunday, Biden called the decision to pick former prosecutor Harris for his 2020 ticket “the best decision I’ve made”, while calling on Democrats to support her.

“Today I want to offer my full support and endorsement for Kamala to be the nominee of our party this year,” Biden said in a post on X.

Here’s what we know about Harris:

Who is she?

Harris, 59, was born in Oakland, California, the daughter of an Indian-born mother and Jamaican-born father.

She attended Howard University in Washington, DC before getting her law degree from the University of California College of the Law, San Francisco.

She began working in the Alameda County district attorney’s office, before shifting to the San Francisco district attorney’s office.

She became San Francisco’s district attorney in 2003. She was then elected California’s attorney general, the state’s top law enforcement role, in 2010 and was re-elected four years later.
