To discuss the latest, Christiane speaks with former Florida governor and current GOP Senator Rick Scott.

After President Trump's inauguration in 2017, one of his first guests to Mar-a-Lago was Chinese President Xi Jinping.

How does this year's DNC fit in with the history of party conventions past? Doris Kearns Goodwin is perhaps the nation's best known presidential historian.

She recently wrote the book "Leadership in Turbulent Times" and she joins Christiane from Boston.

Political conventions are the stage upon which Presidential candidates need to employ one skill above all others: the art of persuasion.

On Day Three of the Democratic National Convention, the party is continuing to make a case for change. Decency and normalcy are the pitch leading up to Joe Biden’s big speech on Thursday, but the convention itself is highly unconventional: speeches via videoconference and keynotes by 17 speakers rather than just one. DNC chair Tom Perez joins the show to discuss his party's platform.

At their unconventional convention, the Democrats are sending a clear message: The stakes -- for the country and for the world -- have never been higher. John Kerry knows what it is to be a Democratic nominee battling a Republican incumbent, having faced off against President George W. Bush in 2004. He joins the program to weigh in on this year's convention and current events.

Apart from its format, the most striking feature of this Democratic National Convention is its unity. Joe Biden’s former rivals are standing up to show their support, including Sen. Cory Booker, whose own campaign for the nomination was all about reconciliation. As he prepares to speak on the final night of the convention, Sen. Booker joins the show to reflect on the stakes in this election.
