Popular pro-Trump YouTube duo Diamond & Silk will testify next week before the House Judiciary Committee as part of a hearing examining “social media filtering and policing practices.” The flamboyant vloggers became a Republican cause célèbre at last week’s Facebook hearings (receiving more attention than more serious issues) after they claimed they were censored by the social-networking site for their right-wing politics. Facebook founder Mark Zuckerberg apologized for “an enforcement error” and said the website had reached out to the duo to resolve the situation—a claim Diamond & Silk disputed, despite email evidence proving them wrong. One of the lawmakers who took up the pro-Trump duo’s cause, Rep. Marsha Blackburn (R-TN), will testify before the panel. And along with Diamond & Silk, experts from the Electronic Frontier Foundation and the News Media Alliance will testify. The committee also extended invitations for representatives from Facebook, Twitter, and Google to appear.
