I don’t know what you’ve been paying attention to (apparently not much) but the Trump administration is pressing Ukraine and others for information regarding the 2016 election, not 2020. Finding out who and what happened is perfectly legitimate, or at least it was during Meuller’s failed investigation.
What’s good for the goose is good for the gander, no? Or is it that you don’t actually give AF about election integrity unless it benefits your own political leanings? Somehow, I’m inclined to believe the later.
