Republican National Committee Chair Reince Priebus chided Hillary Clinton late Wednesday for looking "uncomfortable" during her Commander in Chief interview with host Matt Lauer on NBC.

"@HillaryClinton was angry + defensive the entire time - no smile and uncomfortable - upset that she was caught wrongly sending our secrets," Priebus tweeted.

The Democratic nominee's team shot back at the GOP organization shortly after.

"Actually, that's just what taking the office of President seriously looks like," a Clinton spokesman replied from her account on Twitter.

Trump later took the stage for his interview with a similar look of seriousness, though Priebus did not draw attention the Republican nominee's facial expressions.
