The Booglaloo movement, a fringe-right extremist group dedicated to instigating a second civil war, is one of the groups plotting these attacks.

Even if promoted under the pretext of being peaceful pro-Trump marches, the Boogaloo groups have a track record of plotting events that become flashpoints for political violence.

“We’re seeing fliers on message boards for more localized events by Boogaloo groups in state capitals in Oregon and Washington,” Webster-Jacobsen says, while local officials and law enforcement officials in Michigan and Minnesota warn the groups are planning similar events in those states’ capitals on Sunday.

The chatter is increasingly taking place on platforms like Telegram, where extremists can congregate in closed, invite-only groups.
