The Gennifer Flowers tweet by Trump is described as a gaffe by the panel. Trump was being sarcastic in response to the invitation to Mark Cuban to sit in the front row. Cuban was crowing about it on Twitter that he would be there in the front row.
The MSM went batsh*t when Trump cleverly got them to have to say who Flowers was. The invitation to Cuban is real while Trump was joking about the Flowers' invitation.
Usually they don’t allow a Trump supporter on the panel.
