Greta Van Susteren won’t be on FNC tonight, but that doesn’t mean she’s not working. Politico reports Van Susteren will sit down for an interview with Gloria Cain, wife of GOP candidate Herman Cain. It’s not known when the interview will air, or where it will take place. On her blog this morning Van Susteren wrote, “I am on a plane – so your turn to blog!”

In her place at 10pmET tonight, Bret Baier hosts a Fox News Reporting special: “The Fight for Iowa.” How the Iowa caucuses work and how they got to be “first in the nation.” For more than a year, FNC crews have been in Iowa following the candidates. The special includes interviews with candidates Herman Cain, Michele Bachmann, Newt Gingrich, as well as former VP nominee Sarah Palin, and former GOP candidate Tim Pawlenty.
