The exchange happened during the show’s first few minutes discussing last night’s events at the RNC. The panelists argued whether or not it was proper for Cruz to give the speech he did, and whether or not he was sincere. CNN’s Sunny Hostin tried to defend Cruz, insisting she thought he was sincerely trying to put the party’s platform first, before getting interrupted by Behar with a Hitler analogy:

SUNNY HOSTIN: The Republican Convention is supposed to be about the party’s platform. That’s what it’s supposed to be about---

JOY BEHAR: Have you seen the party’s platform? I think it was in Mein Kampf, the last time I saw that!

HOSTIN: ---But he was really saying was, vote your conscience

BEHAR: Have you seen that platform?

HOSTIN: Vote common decency, Vote constitutional principles-This is what he wants the party to be about.
