YouTube blocked users from commenting live during Tuesday's congressional hearing about hate speech and white nationalism after the broadcast's chat room became flooded with bigoted and anti-Semitic reactions.

"Due to the presence of hateful comments, we disabled comments on the livestream of today's House Judiciary Committee hearing," a YouTube spokesperson said in a statement.
