MSNBC Rachel Maddow producer attacks Kirsten Powers. Powers fires right back, and good. So what does Maddow think about her sexist subordinate?

So an MSNBC producer, Jamil Smith, attacks Fox's Kirsten Powers for explaining her ex-relationship to Anthony Weiner--a relationship that came up because Weiner asked Powers to vouch for him, which she did, briefly, until all the facts came out--and Kirsten fired right back--see screen grab of her tweet, above.

So what does Smith's boss, Rachel Maddow, think about her subordinate's obvious sexism?  Surely she will chastise him--at least.
