Joe Biden has selected Kamala Harris to be his running mate, elevating a charismatic blue-state senator, former prosecutor and onetime 2020 primary rival who has built a reputation as an unyielding antagonist of the Trump administration.

Harris, the daughter of immigrants from Jamaica and India, was the wire-to-wire frontrunner for Biden’s No. 2 job. Her experience as a battle-tested presidential candidate, her efforts leading major law enforcement offices and her political track record of three election wins in California helped her overcome a crowded list of contenders.

"I have the great honor to announce that I've picked @KamalaHarris — a fearless fighter for the little guy, and one of the country's finest public servants — as my running mate," Biden wrote in a tweet Tuesday.

In her own tweet, Harris called joining Biden’s ticket an honor.

Harris will be the first woman, the first Asian American and the first Black vice president if elected. And Biden’s barrier-breaking pick comes at a time of racial reckoning in the country, plunging one of the best-known women of color in politics into a contest against President Donald Trump, who has stoked racial divisions from the White House and on the campaign trail.
