NEW YORK (AP) — The second Republican presidential debate will be broadcast Wednesday on Fox Business Network and Univision, but the exclusive online livestream will take place on Rumble, an alternative video-sharing platform that has been criticized for allowing— and at times promoting — far-right extremism, bigotry, election disinformation and conspiracy theories. By bringing viewers to Rumble to watch the GOP debate, as it did with the first one last month, the Republican National Committee is driving potential voters to a site crawling with content that flouts the rules of more mainstream ones such as Facebook, uh Instagram and YouTube.
