According to the viral claim, Giuliani has announced that Mamdani is officially under investigation for his ties to extremist groups and foreign governments. 

The claim has spread across various online spaces such as X (formerly Twitter), Facebook, and Instagram since earlier this month, garnering hundreds of thousands of views.

The claim has triggered a debate among online users, with many appearing to believe the claim to be true and calling for the denaturalization and deportation of him and his wife. Meanwhile, others dismissed it as fake and called for a fact check to verify its authenticity.

The claim, however, is false, as there are no recent investigations against the Social Democrat. 

There are also no reports of the former Republican mayor making such an announcement, as there are no official statements, press releases, or social media posts by Giuliani available to the public. 

A search on Google for the claim yielded no relevant results by credible news media outlets, which, if true, would have made headlines, sparking nationwide outrage.

A fact check by Grok stated, “The claim shared in the post is misleading. There is no confirmed announcement by Rudy Giuliani that NYC Mayor Zohran Mamdani is officially under investigation for ties to extremist groups and foreign governments.”

Some families of 9/11 victims seek to ban Zohran Mamdani from 25th anniversary commemoration

The claim surfaced as Mamdani is facing a growing campaign from some families of 9/11 victims, who are seeking to bar him from the city's 25th anniversary commemoration ceremonies next month.

When a reporter asked the mayor about the campaign, he said, “I wonder how you feel about the fact that they’re trying to keep you away.” 

"I will proudly honor the families, the survivors, the first responders, forever impacted by that horrific attack by standing alongside them at this year's 9/11 commemoration, reaffirming that we will never forget the solemn day felt by all of us who call this city home and, frankly, by all of us who call this country home," he said.
