Guilfoyle, the fiancée of Donald Trump Jr, was speaking at the dinner in Hollywood, Florida when she shared her hope that Democrats would lose seats in Congress and be forced to give up control of the White House.
Just to add some context from memory. Jeb was doing an event to rally his supporters but everyone was so hyped up they kept interrupting him during his speech. He politely asked them to save the clapping till the end. When he finally finished no one reacted so he had to tell them to clap.
That's some really neat context. I wasn't overly concerned with Jeb at the time, since I had no interest in any of the R candidates, but the 'please clap :(' sure did the rounds.
I can see now, though, that Kamala Harris was certainly aware and trying to not hit the same landmine during the DNC. Watching her try to politely tell the crowd to shut up for what felt like an hour got quite painful.
