The next Republican presidential debate is Jan. 28 in Des Moines, just before the Iowa caucuses, Fox News announced last month. The two-hour debate is scheduled to take place at the Iowa Events Center.

Fox News (not counting its business channel) will be hosting a Republican debate for the second time this election cycle. The debate is scheduled to begin at 9 p.m. EST on Fox News Channel, with access also available on the network’s radio station, mobile app and website,

While the criteria for candidates to qualify won’t be announced until closer to the event, the debate will be a crucial moment for Republicans, as it will be their last meeting as a group before the first nominating contest in Iowa on Feb. 1. 

After the sixth debate, hosted by the Fox Business channel, knocked Kentucky Sen. Rand Paul and Carly Fiorina off the main debate stage, candidates will likely be on edge to see who will remain at the next showdown.

The prime-time lineup for the FBN debate was Donald Trump, Texas Sen. Ted Cruz, Florida Sen. Marco Rubio, Ben Carson, former Florida Gov. Jeb Bush, New Jersey Gov. Chris Christie and Ohio Gov. John Kasich. Fiorina, former Arkansas Gov. Mike Huckabee and former Pennsylvania Sen. Rick Santorum participated in the undercard debate.

The moderators for the next GOP debate will be the same set as Fox News used for its first debate last August: “Special Report” anchor Bret Baier, “Fox News Sunday” host Chris Wallace and Megyn Kelly, anchor for “The Kelly File.” The previous debate pulled in 24 million viewers, USA Today reported, making it the channel’s most-watched non-sports program ever.
