Fox News’ Megyn Kelly said this week that it was “shocking” to watch Marco Rubio’s debate performance over the weekend, and said he appeared to be “too terrified” to abandon his talking points.

“I’ve heard some people say that it wasn’t that Rubio, it isn’t that he’s a robot,” she said Tuesday evening in a radio interview on Kilmeade & Friends. “It’s that he’s too cautious. You know, and he may have just been too terrified to deviate from message.”
