The House Homeland Security Committee issued a subpoena on Wednesday to Jim Watkins, the owner and operator of 8chan, to discuss extremist rhetoric on social media.

Catch up quick: Bipartisan Committee leaders sent Watkins a letter Aug. 6 asking for him to testify on his efforts to "investigate and mitigate the proliferation of extremist content" on 8chan. The anonymous forum has been linked to at least 3 white supremacist attacks this year — most recently the mass shooting at a Walmart in El Paso in which Hispanics were targeted.

Of note: The site’s founder Fredrick Brennan has called for the site to be shut down, saying it offers a "receptive audience for domestic terrorists." He stepped away from working with the site’s owners in December.

What they're saying:

"In recent years, violent extremist content has proliferated on both large and small social media platforms. ... Receiving testimony from Mr. Watkins is critical to our oversight on this matter."
— per a statement from Committee Chairman Rep. Bennie Thompson (D-Miss.) and ranking member Rep. Mike Rogers (R-Ala.)

Why it matters: Since the 2016 election, reporters and researchers have uncovered over 1,200 instances in which political groups use websites disguised as local news outlets to push their point of view to Americans.

Nationalism and authoritarianism threaten the internet's universality

Governments around the world, prompted by nationalism, authoritarianism and other forces, are threatening the notion of a single, universal computer network — long the defining characteristic of the internet.

The big picture: Most countries want the internet and the economic and cultural benefits that come with it. Increasingly, though, they want to add their own rules — the internet with an asterisk, if you will. The question is just how many local rules you can make before the network's universality disappears.

The Democratic fight to shape Biden's climate policy

Left-wing climate activists don't want Joe Biden getting advice from people with credentials they don't like — and they're increasingly going public with their campaign.

Why it matters: Nobody is confusing Biden with President Trump, and his climate platform goes much further than anything contemplated in the Obama years.
