No. The Viking guy is Jake Angeli. Michael Vos is the other guy, a journalist for a Dutch news network, (and yes, he is Pelosi's son-in-law) doing his job conducting an interview.
The question in your headline "who is he?" refers to "this other dude", not to "Viking Guy."
This kind of meme is a great example of how fake news gets disseminated on the internet. Post a pic, post an "explanation" of what the pic is about, and people will believe the explanation. There is no dastardly connection between the two men.
