Barack Obama is set to speak in his hometown Chicago for the second day of the Democratic National Convention - you can follow his speech on our live page. Although his career rocketed earlier, the former US president and Kamala Harris belong to the same generation and have moved in overlapping political orbits.

When did Barack Obama and Kamala Harris meet for the first time?

They met at a California fundraiser in 2004. Ms Harris became an early supporter. In 2007, while she was a San Francisco district attorney, she was in the crowd of more than 15,000 people when Mr Obama announced his longshot bid for the White House. She then served as his California campaign co-chair.

How has Obama helped raise her profile?

As she was campaigning to become California's attorney general in 2010, the president appeared at a Los Angeles rally and called Ms Harris "my dear, dear friend". She won the election, and was later given a coveted speaking role at the 2012 Democratic National Convention for Mr Obama's re-election. He also endorsed her, alongside Joe Biden, for the California Senate race in 2016.

What about now?

Though Barack and Michelle Obama waited several days to endorse Ms Harris until it was clear that there were no challengers and she was the party choice, the pair released a video of them calling her to formally announce their support for her campaign. The Democratic nominee has also relied on many of Mr Obama’s old hands to help run her campaign.
