The context is that he was posting on a news article about a fake police officer with SS tattoos carrying weapons to intimidate BLM protestors in Las Vegas.

I used samac.io to search his deleted comments.
A few more comments:
Yes, to be clear, I’m not accusing people who are simply actually unaware of it of anything. However, it’s an incredibly well-known symbol that the nazis used, maybe right behind the swastika and the SS symbol. Someone who is a politician and has had it tattooed on their body for 20 years could not be unaware of what it means.
It’s also already been shown through his deleted r*ddit posts defending other people’s SS tattoos that there’s no way he was unaware.
