They're saying that, but I'd class it as internet gossip. The rumor started about 2 weeks ago. Realistically, the squatters are Venezuelan gang members with guns, way different animal than Antifa, etc.... If Colorado had balls they'd send in SWAT or the National Guard.
In the last few years, we've essentially let an invading army through our border unimpeded. It's going to talk a lot to fix that, and some of it will never be fixed.
