Story highlights Bill Clinton is campaigning for his wife's presidential bid in New Hampshire

On Sunday, he spotlighted supporters of her opponent for what he called "sexist" attacks and harassment

(CNN) Bill Clinton lashed out at "sexist" and "profane" attacks on Hillary Clinton and her supporters by proponents of Bernie Sanders, and accused them of harassing those who don't back the Vermont senator's campaign or disagree with his policies.

Speaking in New Hampshire on Sunday, Clinton delivered an extended rebuke of the Sanders supporters, whom he said subject people who back his wife to "vicious trolling."

He described a progressive blogger who wrote a favorable column about the former secretary of state but was compelled to post it under a pseudonym out of fear of blowback from Sanders proponents.

"She and other people who have gone online to defend Hillary and explain -- just explain -- why they supported her have been subject to vicious trolling and attacks that are literally too profane often -- not to mention sexist -- to repeat," Clinton said.

With just hours to go before voting starts in New Hampshire, Clinton is solidly trailing Sanders in the state, with the latest CNN poll of polls average showing the Vermont senator up 14 percentage points.
