Last Saturday, more than 200 cities from Spokane to Scranton saw modest rallies for a cause that was so pure, so unifying, that who in their right mind wouldn't want to join in?

Save the Children was the chant and child trafficking, the scourge. But lately, that movement, to save the children,

has been engulfed by another movement

that has filled the streets in its name.

These rallies, in fact, are just the latest instance of QAnon,

a group and a conspiracy theory,

spilling out of their online domain into what was

formerly known as real life. This we know from the reporting of NBC News investigative reporter

Brandy's Adrosny, along with reporter Ben Collins. Brandy, welcome back to the show.

Thanks so much. If I lived in, say, Grand Rapids or

Pueblo, Colorado, or Evansville, Indiana, and I tuned into my local news last weekend,

how would they have described what happened in my neck of the woods? Well, you probably would have seen a correspondent standing in front of a group of a couple dozen people holding signs saying...

Wherever there are people, there's the potential for human trafficking, according to the Department of Homeland Security.

Speakers at the event believe the issue of human trafficking needs to be brought to the forefront,

both in the U.S. and around the world.

A group called Operation Wake Humanity held signs

and chanted save our children to passing cars from the parking lot of the old Southside Kmart.

And you would see men, women, children, old, young carrying these signs.

They're dotted with handprints that are stained blood red.

Often they have shirts that say, I'm not for sale on the kids.

And they're shouting, save the children, save the children.

I'm really impressed with all these people out here. They are for Save the Children.
