When Erin Burnett asks Reince Priebus regarding Ben Carson's anticipated endorsement of Donald Trump, Priebus responds (beginning at 0:16): ".... [inaudible] I mean that's what you guys are reporting, I, I, I don't know w-, what the details are of that but, you know look, it's, ah [inaudible] Dr. Carson's done, did a great job, I mean he's been expanding our party. He's an important voice in our party. He's a good man, ummmm, but I don't know the details of it, but certainly there're a lot of endorsements going on around the country right now, ahhhh, and if it's true then that's a, that's a, that's a, that's a, that's a big get ..."
At three different times in this brief video the RNC Chair displays variations of a shoulder shrug.
When he says, "... you know look it's ..." (0:22) both of his shoulders elevate.
Again at 0:35 as he says, "... ahhhh ...", both shoulders shrug - although it's less prominent then the previous display.
Then during 0:37 (in above still image) when he says, his second of five consecutive "... that's a ...", his shrug is exclusive to his left shoulder. This is one excellent example of a what is known as a Partial Emblematic Slip.
An emblem has an accepted regional, national or universal meaning and is nearly always performed consciously (but not always). Emblems are often used in place of words because of their very specific meanings (e.g., a head nod yes, a head shake no, the middle finger, etc.). This third example of Priebus' shrug however, was a partial emblem because it was only on his left. It was subconscious and thus a slip - and thus leakage of his true feelings.
A shrug indicates either, "I don't know", "What can I do?" or "What does it matter?". Mr. Priebus either believes Carson's endorsement of Trump has no significant consequence or there's nothing he/the RNC can do to stop Trump.
