“Every time I think of Trump, I get allergic,” Clinton croaked in between coughs, after drinking some water and patting her chest. “Boy, we have 63 days to go.”
The Democratic presidential nominee, who has suffered coughing attacks on the campaign trail, coughed for nearly two minutes. The crowd cheered her on, saying, “We love you Hillary!”
Trump’s campaign manager, Kellyanne Conway, was quick on the rebound with a jab about Clinton’s lack of face time with the press.
“Must be allergic to media. Finally spent a minute [with] them,” Conway posted on Twitter.
It wasn’t long before video of Clinton’s latest coughing fit circulated on social media and the hashtag #HackingHillary began trending on Twitter with tens of thousands of tweets.
