Speaking to reporters outside her campaign plane Thursday morning, Hillary Clinton responded to a question about the below tweet from RNC chairman Reince Priebus urging her to "smile" more. Asked if she believes there is a "double standard" in the presidential race for women, she replied: "I'm going to let all of you ponder that last question." <blockquote class="twitter-tweet" data-lang="en"><p lang="en" dir="ltr"><a href="https://twitter.com/HillaryClinton">@HillaryClinton</a> was angry + defensive the entire time - no smile and uncomfortable - upset that she was caught wrongly sending our secrets.</p>— Reince Priebus (@Reince) <a href="https://twitter.com/Reince/status/773694140404170752">September 8, 2016</a></blockquote> <script async src="//platform.twitter.com/widgets.js" charset="utf-8"></script> <blockquote class="twitter-tweet" data-lang="en"><p lang="en" dir="ltr">Actually, that’s just what taking the office of President seriously looks like. <a href="https://t.co/Pyn92mesom">https://t.co/Pyn92mesom</a></p>— Hillary Clinton (@HillaryClinton) <a href="https://twitter.com/HillaryClinton/status/773697548389380097">September 8, 2016</a></blockquote> <script async src="//platform.twitter.com/widgets.js" charset="utf-8"></script> "I think there will be a lot of PhD theses and popular journalism writing on that subject for years to come," she said. "I don't take my advice and I don't take anything seriously that comes from the RNC," Clinton added. "We were talking about serious issues last night. I know the difference between what we have to do to fix the V.A., what we have to do to take the fight to ISIS than just making political happy talk. And I had a very short window of time in that event last night to convey the seriousness with which I would approach the issues that concern our country." She continued, attacking her opponent: "Donald Trump chose to talk about his deep admiration and support for Vladimir Putin. Maybe he did it with a smile, and I guess the RNC would have liked that."
