Just six weeks away from the Iowa caucuses, Republican presidential hopefuls returned to the debate stage Wednesday night for their last chance to speak directly to a national audience before the primaries begin.

Former New Jersey Gov. Chris Christie, former U.N. ambassador Nikki Haley, Florida Gov. Ron DeSantis and businessman Vivek Ramaswamy all squared off to try and make the case why they should be the GOP nominee.

Meanwhile, former President Donald Trump, the race's far and away frontrunner, will be in Florida at a closed-door fundraiser.
