Michelle and Barack Obama gave resounding endorsements of Kamala Harris on Tuesday night at the Democratic National Convention, exhorting party supporters across the US to turn out and vote to defeat Donald Trump in November.
"Hope is making a comeback," Mrs. Obama told the crowd at the DNC in Chicago, echoing her husband's campaign promise of "hope and change".
In their back-to-back speeches, the Democratic Party's most popular figures praised Ms Harris, while excoriating Trump - whose presidency was characterized by "bluster and chaos", in the words of Mr Obama.
However, the couple also warned their party not to lose sight of what remains an extremely tight race amid the enthusiasm for Ms Harris's campaign. They stressed the election would be decided in a handful of key swing states.
