Will this come up in the TS/Sci renewal?

My brother married a foreign national and they are now separated. She had a few mutual friends with me. Things got messy between them and i heard through the grapevine she filed a vawa against him and got her greencard that way after they separated. Vawa is for extreme mental or physical abuse. For his TS renewal is there anyway this could come up? Do I need to warn him? There’s no court hearing for her to get it and it’s supposed to be confidential to protect her.

But if he has to submit her alien number in his renewal, will they look into how she got her green card and see she accused him of that? For the renewal does he need to submit a photocopy of her greencard even though they are separated?
