Democratic presidential candidate, Joe Biden has named Kamala Harris as his running mate making her the first black woman and South Asian American in the role.
Once a rival for the top job, the California senator of Indian-Jamaican heritage had long been considered the front-runner for the number two slot.
Mr Biden will face President Donald Trump in the election on 3 November.
After Tuesday’s announcement, Ms Harris tweeted that Mr Biden “can unify the American people because he has spent his life fighting for us and as president, he will build an America that lives up to our ideals”.
She also tweeted, “I’m honoured to join him as our party’s nominee for Vice President, and do what it takes to make him our Commander-in-Chief”.
The Biden campaign said that Mr Biden and Ms Harris will deliver remarks in Wilmington, Delaware, on Wednesday afternoon on working together to restore the soul of the nation and fight for working families to move the country forward.
At a White House news conference on Tuesday, President Donald Trump, a Republican, said he was pleased with Mr Biden’s choice, adding that Ms Harris did “very, very poorly” in her effort to become the Democratic nominee.
Ms Harris will take part in a debate with Mr Trump’s running mate, Vice-President Mike Pence, on 7 October in Salt Lake City, Utah.
Mr Biden, if elected will be the oldest US president in history as he will turn 78 in November.
