Megyn Kelly Won Thursday's GOP Debate

The Fox News debate moderator took no prisoners.

Republican presidential candidates butted heads Thursday night in the final debate before the Iowa caucuses, but the real star was Fox News host and moderator Megyn Kelly

Kelly was particularly sharp in her performance, calling out businessman Donald Trump as "the elephant not in the room," catching Sen. Marco Rubio (R-Fla.) flip-flopping on immigration, and criticizing former Florida Gov. Jeb Bush's relentless attack ads on other Republican candidates. 

Watch Kelly confront the candidates above.
