Is Hillary Clinton cracking under pressure? The presidential candidate banned members of the public and the press from an event this week, raising concerns about how she is handling the spotlight.

For the past few months, Clinton has been pressed by environmental activists, and blasted by protesters about her stance on mining. In one incident, she was confronted head-on by a miner who wanted to know why she pledged to shut down the mines.

Such encounters have not boded well for Clinton , her party's likely nominee, as her poll numbers continue to decline.

In the face of that mounting pressure, she suddenly announced she would prohibit specific groups from attending her latest event at a local coffee house in Stone Ridge, Virginia.  Clinton banned the general public as well the media from attending the event.

"Due to space constraints at this venue, this event will be invitation only and pooled for press," the event description said.

Could Clinton be hoping to avoid any more gaffes that could bring her poll numbers further south? Though she still maintains a modest lead in a new national poll, the GOP is unifying around presumptive Republican nominee Donald Trump.

Do you think Hillary made the right move by banning press? Let us know in the comments!
