NBC's Megyn Kelly delivered a public apology Wednesday for suggesting that she thought wearing blackface on Halloween was OK.

Facing a wave of backlash, Kelly apologized to colleagues in an email Tuesday, and on Wednesday said she was sorry on her show.

“I was wrong, and I am sorry,” she said. “One of the great parts of sitting in this chair each day is getting to discuss different points of view. Sometimes I talk; sometimes I listen. And yesterday, I learned.”

During her show Tuesday, Kelly asked, "what is racist?" and went on to wonder whether it was a bad thing for someone of one race to try and change their appearance to look like another.

“You truly do get in trouble if you are a white person who puts on blackface at Halloween or a black person who puts on whiteface for Halloween," Kelly said. “Back when I was a kid, that was OK, as long as you were dressing up as, like, a character."

Among those who called on Kelly to issue a public apology, after she sent an email to NBC staff, was her colleague Al Roker, who said early Wednesday morning, "she owes a bigger apology to folks of color around the country."
