Students rebuked Chelsea Clinton for attending a vigil for the victims of the New Zealand mass shootings at New York University.

A video posted by one of the students on Twitter showed a young woman confronting Ms Clinton and suggesting her “rhetoric” had helped cause the Christchurch attack.

But the person who originally posted the clip deleted her Twitter account following a backlash from people defending Ms Clinton.

“This right here is the result of a massacre stoked by people like you and the words that you put out into the world,” the female activist in the video, reportedly a student at NYU, could be heard telling Ms Clinton on Friday.

“And I want you to know that and I want you to feel that deep inside. Forty-nine people died because of the rhetoric you put out there.”

Ms Clinton responded by saying: “I’m so sorry that you feel that way.”

A male student was then heard shouting from behind the camera: “What does ‘I’m sorry you feel that way’ mean? What does that mean?”

Although the student who shared the video deleted her account after it went viral, the video was widely re-posted by many others supporting Ms Clinton, arguing she did nothing to merit such aggressive hectoring.

The incident is believed to have stemmed from a recent remark by Ms Clinton about Minnesota Democrat Ilhan Omar, one of the first two Muslim women elected to Congress in 2016.

After Ms Omar suggested the Israeli lobby had too much influence on US policy, Ms Clinton tweeted: “We should expect all elected officials, regardless of party, and all public figures to not traffic in antisemitism.”

On Friday, Ms Clinton, who is pregnant with her third child, tweeted her condolences following the Christchurch attack.
