Howard Dean calls Trump a "coke user" on Twitter

Dean’s tweet may prove controversial for mentioning — without evidence — illicit drug use and the Republican presidential nominee in the same breath.

Trump frequently and audibly sniffled Monday night during his clash with Hillary Clinton at Hofstra University in Hempstead, N.Y.

The real estate tycoon’s snorts were picked up by the television audience, which experts predicted may have exceeded 100 million people.

More viewers raised questions about Trump’s health on social media, an interesting twist after the Republican candidate seized Clinton’s health scare earlier this month to raise questions about her fitness to serve as president.
