Cap from the Biden video. Her face never appears clearly, this is about as close as it gets I think.
I just watched the whole thing because I chose to see for myself. Watch it yourself if you want, or don't, but I'm not here to convince anyone of shit. It's Hunter getting a foot job from some girl while he smokes crack. It's not like it's any worse than pron. If you watched it you'd realize it's definitely a girl. Her identity is not clear, but her voice is on the video.
