Rumors about why Donald Trump was audibly sniffling during the first presidential debate ran rampant on social media Monday night.

Howard Dean, the former governor of Vermont and a prominent Hillary Clinton surrogate, went as far as to question whether Trump’s sniffles were because of cocaine use.

Dean, who was formerly chair of the DNC and ran for president in 2004, has railed against Trump for his refusal to release his tax returns, calling him a “fraud,” and for advancing claims that President Barack Obama was not born in the US.

Some on Twitter also speculated Trump may have caught a cold before the debate.
