Why is Melania Trump suddenly talking about Epstein?

It could be because Brazilian model Amanda Ungaro is about to expose her.

Amanda Ungaro divorced her husband Paolo Zampolli, who is a close friend of Trump's. And according to her, Zampolli used his place in Trump's government to get ICE to detain her. But now she is out, and yesterday she posted this to Melania:

"I will tear down your corrupt system, even if it's the last thing | do in my life. I will go all the way—I am not afraid."

@randahl Why does she threaten to expose them and not simply expose them right now? What's the reason for waiting? Does she hope for some kind of deal?
@StephanMatthiesen @randahl
Maybe she needs to wait for some lawyer to greenlight her revelations. Or she's upping the ante for an exclusive book contract or something (no offense).
