Delaware Senate candidate Christine O'Donnell (R) will sit down Tuesday night for her first major TV interview with Fox News's Sean Hannity.

O'Donnell made a round of media appearances last Wednesday morning after she upset Rep. Mike Castle (R-Del.) in the Senate primary. But after news broke that she once "dabbled into witchcraft," O'Donnell pulled out of two Sunday show appearances, including Fox News Sunday.

Hannity's show is a comfortable setting for conservative candidates. Sarah Palin recently said the Delaware Republican, whom she endorsed in the primary, should "speak through Fox News."
