(CNN) COLUMBIA, S.C. – Gov. Nikki Haley will endorse Sen. Marco Rubio ahead of Saturday’s South Carolina Republican presidential primary, an adviser to the governor tells CNN.
Rubio and the other GOP contenders are set for one last nationally televised chance to make their cases before the crucial primary.
A pair of town halls, which start at 8 p.m. ET on both Wednesday and Thursday, will be moderated by CNN’s Anderson Cooper. The first night features Ben Carson, Ted Cruz and Rubio, and the second night’s lineup is Jeb Bush, John Kasich and Donald Trump.
