Kirsten Powers was at the top of her game last night as she faced down Bill O’Reilly over his Ebola fear mongering.

You may recall that the night before, O'Reilly worked himself into a seething lather as he called for the firing of CDC head Dr. Tom Frieden and demanded that West Africans be barred from the U.S.

Powers told O’Reilly early on, “I’m not going to call you hysterical but it’s bordering on hysterical.” She never let up.

I’ve got my quibbles with Powers (in that I’ll never understand how or why she gets in bed with Fox’s propagandizing) but when she stands up against Fox's BS, she’s one of the best.
