Vice President Kamala Harris' historic tour to Africa has drawn to a close - and her trip has been described as a hopeful political boost to get black US voters backing Biden.

Harris was 'welcomed home' in many countries, including Zambia, where she once visited as a little girl when her grandfather worked there.

It caused the president of the country, Hakainde Hichilema, to describe her presence as being 'like a homecoming' while calling her a 'daughter of our own country'.

Aside from some tactful international diplomacy in which billions of dollars of U.S.

investment was promised, it is hoped the visit may resonate with black Americans as Biden gears up for a second White House term.

In Ghana, President Nana Akufo-Addo told Harris 'you're welcome home.' In Tanzania, a sign in Swahili told Harris to 'feel at home.' 

The greetings were a reflection of the enduring connections between the African diaspora in the United States and Africans themselves, something that America's first black vice president fostered during her trip. 

Although her historic status has led to extreme scrutiny and extraordinary expectations in Washington, it was a source of excitement over the past week.
