Is this Walz? Sure looks like it.

And speaking of Tim Walz, take a look at this video, which seems to be Walz dancing.  Look at the guys in the background.  Where was this taken?  Any reporter wanna try to authenticate it?

 

The location should be easy to identify from the unusual light fixtures on the ceiling and the lighted outline around the elevator and doors.  Once that's known, then from the date on the video's metadata one should be able to learn what event was taking place at that hotel.  Any bets?
