The reason they are so focused on Trump, is because they hate him.
I've already acknowledged that. Trump ran on draining the swamp. You can like him or dislike him based on his policies, but this has just proven he's part of the swamp, which is why he never drained it.
Trump has his own questionable history with sex assault, same as Bill Clinton, whether or not they flew on his plane, which they both did. (See how easy it is to say Trump and Clinton are both unfit) That's not the issue. The issue is how multiple administrations have seen it unfit to release the files because they were both complicit. This is not a partisan issue
