In December of last year, according to court documents, Bruno Kua was feeling restless.

The election had long been called for Joe Biden, but President Trump continued to claim

without evidence that it was stolen.

So Kua, an 18-year-old from Georgia, wrote on social media, quote,

I don't want to sit here and watch. I want to fight. On January 6th, Kua traveled to DC with his parents,

both Trump supporters for the president's stop the steel rally. After the rally, they marched to the capital,

where a scuffle broke out on the stairs. Bruno asked his parents if he could get a closer look.

According to the government, he made it inside and ran into police outside the Senate chamber,

where he shoved them out of the way. Video footage places in there. And it's just then that one of the

rioters was telling a handful of others they shouldn't be sitting in Vice President Mike Pence's chair.

Kua responded like a typical 18-year-old.

If they can steal an election, we can't send their chair. No! We're not putting up with that either.

If they can steal an election, he says, why can't we sit in their chairs? Other rioters argued it wasn't great optics for their cause.

We are war! We can't lose the I-O war!

An older man tells Kua, it's an I-O war, a military term, information operations.

We can't do it!

Now, Kua is the youngest person charged so far in connection with the capital riot.

And a new NPR investigation has revealed how his political radicalization online echoes another kind of extremism from a decade ago.

I think you're causing me to realize more parallels with these folks and some of the jihadis who understand the world in this very strict, good versus evil kind of way.

Consider this, the capital siege put a spotlight on something that usually takes place in the shadows of the internet, young people in America being radicalized, and in larger numbers than ever before.

Our investigations team reveals how it's happening.
