The mob violence that descended on the U.S. Capitol on Wednesday was the culmination of weeks of incendiary rhetoric and increasingly feverish planning – much of which took place openly on websites popular with far-right conspiracy theorists.

Jared Holt spends a lot of time on those websites. He's a visiting research fellow with the Atlantic Council's Digital Forensic Research Lab, where he has been focused on extremist online activity.

TikTok is toughening its stance against the QAnon conspiracy theory, expanding its ban to all content or accounts that promote videos advancing baseless ideas from the far-right online movement.

Facebook is banning all content that "denies or distorts the Holocaust," in a policy reversal that comes after increased pressure from critics.

The House overwhelmingly approved a resolution condemning QAnon, the fringe movement that promotes wide-ranging conspiracies about the U.S. government and yet has enjoyed a rising tide inside conservative politics in part because of tacit encouragement from President Trump.

The measure passed 371-18, with one GOP member voting present.

QAnon is a "collective delusion," said House Rules Chairman Jim McGovern, D-Mass., "We all must call it what it is: a sick cult."

President Trump addressed the baseless, far-right QAnon conspiracy theory directly for the first time on Wednesday, saying he didn't know much about the online community and its followers other than "they like me very much."

"I heard that these are people who love our country," Trump added in response to a question about the conspiracy community during a press briefing at the White House.
