In the excerpt, which was presumably the lead portion of the story, the station labeled the group as “far-right” without ever identifying the group or stating any of its alleged “far-right” beliefs. It sounds like the wife of the organizer is from Guyana, so that would seem to shoot down any notion that they are “white-supremacists” or neo-Nazis.
Update: I looked at the full article and it does indeed mention the groups that are “believed” to be sending members, but the only person specifically identified as a member of the group - the Proud Boys - belongs to a group that has repeatedly been slandered and mischaracterized, and I would not be surprised if that was true of some of the other groups listed as possible attendees.
