As CNN's Anderson Cooper was covering the aftermath of the attack in Manhattan, New York, protesters made their voices heard, calling the media outlet "fake news" and a terrorist organization (video below).
Cooper was reporting live on the evening of Oct. 31, covering the incident that killed eight people and injured 12 after a truck plowed into a crowd, according to the Daily Mail.
In the video, a man walks behind Cooper and holds his hands in the air while yelling over and over, "CNN is fake news!" using President Donald Trump's catchphrase that he has frequently used at campaign rallies and at press events.
At another time during Cooper's reporting, somebody stood in the shot with a banner that said, "CNN is ISIS."
The protest was likely organized by far-right activist and Trump supporter Laura Loomer, a former Project Veritas member who made headlines after ride-hailing service Uber banned her for speaking out against Muslims and refusing rides with Muslim drivers, according to Business Insider.
"There's no such thing as a moderate Muslim," she tweeted on Oct. 31. "They're ALL the same. It's time for us to accept this reality. I refuse to watch more [people] die."
The alleged Manhattan attacker, Uzbek immigrant Sayfullo Saipov, has reportedly said he carried out the attack for ISIS and was proud of his actions, reports The Associated Press. He also had a large amount of ISIS propaganda and had been planning to plow the truck into a Halloween crowd for months, authorities believe.
But ISIS has not taken credit for orchestrating the attack that authorities said was inspired by the terrorist organization.
"How many more people need to die before everyone agrees that Islam is cancer [and] we should never let another Muslim into the civilized world?" Loomer tweeted.
Despite the timing, this is not the first time supporters of the far right have worked to trend the "CNN is ISIS" message.
In May, Alex Jones' conspiracy website Infowars launched a contest offering fans between $1,000 and $2,500 for appearing on TV with T-shirts or signs that have the phrase on it. The site said it was an effort to "stand up to the Left's calls for violence against the president and against other Americans for simply exercising their right to promote Americana" and "expose the media's terrorist campaign."
"We encourage everyone to not just hold up signs to point out that CNN is ISIS and that [mainstream media] are terrorists, but to also use this campaign as an example to point out when mainstream media and entertainment writers, editors and hosts are calling for violence against Trump and against his supporters for simply only trying to make America great again," the website said.
