Chelsea Clinton is to blame for the crazed attacker that killed at least 49 mosque-goers in New Zealand on Friday.

The former first daughter was confronted by activists tonight at a memorial service at NYU for the victims.

A video was posted to Twitter — which would likely qualify as a violation of Twitter rules — showing Clinton calmly defending herself amid the hostile accusations.

“. is here at the NYU vigil right now,” Esor tweeted.

“A lot of students feel uncomfortable. People haven’t forgotten the Islamophobic mob she incited against . There is no sense of responsibility,” Esor said in the tweet that is now protected.

The video shows Clinton being accused of being responsible for the attack.

“I am so sorry you feel that way,” Clinton responded, “it was certainly never my intention. I do believe words matter,” she said in apparent reference to Rep. Ilhan Omar’s repeated anti-Semitic comments.

“This right here,” the activist said, waving her arms wildly, “is the result of a massacre stoked by people like you and the words you put out there,” she said, “And I want you to know that,” the woman lectured, “and I want you to feel that deep inside.”

“Forty-nine people died because of the rhetoric you put out there,” the woman said, poking her finger towards Clinton as her backers snapped in approval.

“I’m so sorry you feel that way,” Clinton responded.

In February, Chelsea tweeted a response to one of Omar’s anti-Semitic statements.

“We should expect all elected officials, regardless of party, and all public figures to not traffic in anti-Semitism,” she wrote.

That is apparently what triggered the NYU confrontation.
