Joe Biden will speak about his vision for uniting America to move us forward out of constant chaos and crisis, and for delivering on that promise for all.”Thursday’s primetime programming includes speeches from four of Biden’s former opponents in the race for the Democratic nomination — Sen. Cory Booker, D-N.J., former South Bend, Indiana, Mayor Pete Buttigieg, former New York City Mayor Mike Bloomberg and Andrew Yang — along with two officials who were on his shortlist for running mate: Sen. Tammy Duckworth, D-Ill., and Atlanta Mayor Keisha Lance Bottoms.While Trump has slammed Democrats this week for airing pre-taped DNC speeches, Biden said he doubts the party will ever return to conventions of the past, deeming the new format provoked by the pandemic landscape “inclusive,” “creative” and “a template for the future.”Here is Thursday’s lineup of speakers:Sen.
