Trump never turned Epstein in.

Trump didn't even kick him out of Mar a Lago until a full 15 months AFTER he was charged with soliciting sex crimes from a minor.

Trump also never testified or gave any information to the FBI either. 

What he did do was apparently spoke on the phone once to one of the victims lawyers who said he was helpful.

Trump was close friends with Epstein for 21 years, including after he was charged.  

If you're trying to tell me it's not possible that in those 21 years Epstein was never able to get any evidence of Trump inappropriately touching someone under 18 years old then I have a bridge to sell you.

I'm not saying Trump was a prolific child predator.  I don't even think that to be the case.  But I do think it's very likely he at least was inappropriate with someone under 18 and that there's evidence of it in those files.
