President Obama and VP Joe Biden will attempt to top Bill Clinton's "prosaic love letter" to Hillary Clinton on the third night of the Democratic National Convention on Wednesday. Other big names scheduled to speak, per the Los Angeles Times, include Harry Reid, Gabby Giffords, Jesse Jackson, Sigourney Weaver, Angela Bassett, and Michael Bloomberg, who is expected to endorse Clinton after initially mulling a run as a third party candidate. Survivors of the Orlando shooting will also appear. But all eyes will be tuned on VP hopeful Tim Kaine as he delivers what ABC News calls "one of the most anticipated speeches" of the night—his first real chance to introduce himself to voters.
