Want to tune in for the first GOP presidential debate? Here’s how to watch

It's being moderated by Fox News hosts Bret Baier and Martha MacCallum. Unlike some previous presidential debates, which have been simulcast across a number of major networks and cable channels, the first forum is airing exclusively on Fox News and the Fox Business Network as well as on Fox's website and other streaming and digital platforms. In lieu of the network's YouTube channel, the Republican National Committee has partnered with Rumble — a video sharing platform popular with some conservatives — to livestream the debate.
