During Wednesday night’s Republican debate, New York Times columnist Charles Blow tweeted a remark about Mormonism that caused a bit of a stir. Following a couple days of no response from him or the paper, this morning, Blow apologized for the comment, calling it inappropriate.

His original comment, in response to Mitt Romney’s statement about two-parent households, was:

Let me just tell you this Mitt “Muddle Mouth”: I’m a single parent and my kids are *amazing*! Stick that in your magic underwear. #CNNdebate

As BuzzFeed explains: many “Mormon men and women wear ‘temple garments’ beneath their clothes as a reminder of their religious commitments, a rough equivalent of Jews’ yarmulkes or tzitzit.”

Asked about the tweet, Romney said, “That is a little surprising, I must admit.” He jokingly added, “I guess we’re finding out for the first time that the media is somewhat biased.”

Friday morning, Blow tweeted an apology:

Btw, the comment I made about Mormonism during Wed.’s debate was inappropriate, and I regret it. I’m willing to admit that with no caveats.

Times spokeswoman Eileen Murphy told BuzzFeed the apology “is enough,” and they are glad Blow acknowledged the comment was inappropriate.
