There haven't been any any trials and won't be unless and until sufficient evidence has been found to charge individuals with breaking any laws - and not only sexual ones, but others such as corruption.
That can't happen until the investigators have combed through all the pages and pages and pages of stuff of which likely, most won't show much more than morally dubious, even only who met or contacted whom and when, rather than illegality.
Also the USA's laws, as in the UK, place the burden of proof on the prosecution, and the presumption on innocence.
So no-one named in any of these millions of pages really can claim to have been exonerated. Not "celebrities", not Wall Street hangers-on, not ex-trade envoys, sacked princes or dismissed ambassadors, not even American presidents; unless fully investigated and cleared officially as having no case to answer; or at least cleared on reasonable doubt.
To claim personal exoneration in advance of any official statement of the fact may even increase suspicions of involvement. You cannot exonerate anyone who was never associated or involved, only exonerate on proving no wrongful association.
