Trump had sexual assault allegations pending against him since the mid-90s. Twenty five recorded incidents in total, from New York ballrooms to the Mar-a-Lago bedroom of his daughter Ivanka.
To date, he's never been criminally prosecuted. The only claims against him have been civil. No DA has taken a case, much less carried it to trial.
That ship sailed before Y2K.
Allegations against Trump are as recent as 2016, assuming you discount White House staff allegations which run up to 2019.
