Four Republican presidential hopefuls will take the stage in Tuscaloosa, Alabama on Wednesday night for the fourth primary debate, the Republican National Committee revealed Monday.

Former New Jersey Gov. Chris Christie qualified for the debate by the skin of his teeth after claiming last month he reached the donor threshold and last week saying he was 'confident' he would meet polling requirements and be on the stage.

Florida Gov. Ron DeSantis, former UN Ambassador Nikki Haley and biotech entrepreneur Vivek Ramaswamy are the other three candidates who qualified for the debate.
