Um... this is a mess.
Someone at the Daily Caller tweeted this
HNIC means "Head N-word in Charge". I guess the person was noting the rapper who calls himself "Rhymes Priebus" like the RNC's Reince Priebus.
Well, someone must have noticed it and the tweet was removed. But, you know the media works, we have it for you to see.
Dumb move, DC.
