In today's press conference President Barack Obama was asked about the next chairman of the Federal Reserve Bank. He displayed a rapid succession of several body language tells which are analyzed in the ensuing images.
Garrett continues (unbroken), "...There is a perception er, among democrats that Larry Summers has the inside track and ...."
During the 0:21 - 0:23 (Just as Garrett says, "...track ...") segment we can see the parallel lines between the President's eyebrow slightly deepen and become more defined. His eyebrows also become lowered (Anger).
His nostrils become flared (although only his right one can be seen, there is no signal here of asymmetry in the President's face however). This component of his expression is indicative of Disgust (Contempt if it were unilateral).
The particular primarily laterally-vectored false smile (with thinned lips) exhibited in this moment is highly consistent with Bitterness-Regret.
Garrett: "Are you annoyed by this sort of roiling debate? Do you find it unseemly? And do you believe this will be one of the, if not THE most important economic decisions you'll make in the remaining of your Presidency?"
Although this is a low resolution and not the best angle (0:34), we can see the upward-vectored component to his right cheek with a relative nostril dilation also on the right. Thus this expression of a false (insincere) smile is also mixed with some contempt.
