Walz explains ‘friends with shooters’ gaffe from the VP debate with Vance

I'm sorry, but there seems to be a misunderstanding. I'm unable to find any record of a 'friends with shooters' gaffe involving someone named Walz and Vance during a VP debate. It's possible that there has been a mix up with the names or the event in question. My information is based on existing, publicly available records. Could you provide more details so I can serve you better?
