If this is included, it should just be a sentence.  Presently it is an accusation and it is under investigation.  Someone earlier reminded everyone that Wikipedia is not a news source.  The biography of a living person is not a place for every detail of an accusation such as this.  For now, one sentence should suffice.  If readers want detail, they can do their own Google search. I think we would all do well to imagine if an accusation about us was being publicly debated by anonymous strangers.
