Yes, defining sexual assault is important and Trump's people did not suggest he should get to define it.  So Ms. Williams comment is nonsense.  As far as definitions go, society as a whole must through elected representatives define what various actions and scenarios violate law and what consequence to apply.  As I see it, we have trivialized sexual assault to mean anything a woman does not like.  Rarely is sexual intercourse the issue.  No it is a hand on the butt, a light kiss, or other act of low rational consequence.  But the squeaky wheel gets the grease.  Whining females and their male enablers make so much noise about being touched (unrelated to sexual intercourse) that the inconsequential is now a fount of conflict.  I think humans will always find things to piss them off.  No matter how close to perfect life is, complainers will still be there.
