Joe Biden has officially chosen Senator Kamala Harris as his running mate for the 2020 US Presidential election.

After announcing the news in an e-mail blast and text message to his supporters, Biden confirmed his selection in a tweet on August 11:

Joe Biden's campaign website has since been updated to feature a picture of Biden and Harris, as well as a biography about the new VP candidate's life and career.

Shortly thereafter, Harris said in a tweet:

CNN reports that Biden and Harris will deliver remarks from Delaware, Biden’s home state, tomorrow, August 12.

Speculation as to who Biden was going to select had been mounting in recent days. Harris was always among the contenders as the former Vice President had publicly committed to choosing not only a female but a person of color.

The New York Times notes that Harris “is the first Black woman and the first person of Indian descent to be nominated for national office by a major party, and only the fourth woman in history to be chosen for one of their presidential tickets.”

Harris, who was among the many contenders for the Democratic presidential nomination until she suspended her campaign last December, is also the second African American woman and the first South Asian American to serve in the United States Senate, where she represents the state of California.

The news of Biden's selection comes just days before the Democratic National Convention is set to begin on August 17. There, the Democratic Party will formally nominate its presidential and vice-presidential candidate.

The 2020 US Presidential Election will be held on Tuesday, November 3, 84 days from now.
