The Mystery of K... Revealed!

This morning, we presented you with the biggest question since, say, why the latest Vanity Fair has a 11-page spread on the saga of 5th Avenue hawks Pale Male and Lola six months after the fact.
Photographer Jennifer Snow caught a special moment of Tucker Carlson being handed a business card from a mysterious "K" character, in which said character expresses their hurt at not being invited to Tucker's MSNBC party. We asked for your help in determining "K's" identity, and you rose to the occasion.
Your guesses, in order of likelihood:
Kate Zernike - Some of you even identified a "Z" on the business card.
Katie Zezima - Same as above.
Kelefa Sanneh - "Is referred to as "K" around the Arts department."
Kit Seelye - "Maybe she was uninvited since she's no longer on the political beat?"
Paul Krugman - "The word 'believe' is underlined. Does this signify a private joke between Tucker and 'K', maybe one about the Christian right?"
Bill Keller - He's "tender-hearted."
Chelsea Clinton - "Known to close associates as 'Ms. Kink.'"
Kay Graham - "No, wait, she works at the WaPo. And she's dead. Which would totally explain why she's now at the Times, right?"
