MANY stories at the time, e.g.,

.
Ultimately, DoJ decided not to prosecute.  
Ultimately, Gaetz did NOT sue anyone for defamation which would have required that he be deposed under oath and for the evidence to be presented in court.
.
Gaetz paid Greenberg to pay the girls to protect himself from being charged directly. Kind of like Eric Trump being thrown under the bus by Donald Trump.

From the deposition transcript, page 20:
Q. Mr. Trump, are you currently the person with ultimate decision-making authority for the Trump Organization? 10:15:06
A. No. 10:15:11
Q. Who would that be? 10:15:12
A. My son Eric is much more involved with it than I am. I've been doing other things. 10:15:16
And I guess you could say on something major, final decisions, whatever. But I've been much less involved in it than over the last five or six years than ever before.
