Stage readied in Delaware for Kamala Harris speech

The Democrats' historic boundary breakers were set to join forces on the third night of the party's national convention.

Barack Obama, Hillary Clinton and Kamala Harris are all addressing the virtual convention Wednesday night in an effort to mobilize the diverse coalition Joe Biden will need to defeat President Donald Trump this fall.

Preparations were underway at the Chase Center in Wilmington, Delaware, where Harris was set to deliver her speech.

Harris, Biden's running mate and the first Black woman on a major party ticket, will deliver highly anticipated remarks that will serve as her introduction to millions of voters.
