In N.Y.C. Mayor’s Race, Mamdani Responds to a Call for His Deportation

Vickie Paladino, a councilwoman from Queens, called Zohran Mamdani a “radical leftist” who hates America, and warned against “future Zohrans.”

June 3, 2025

In his surprising rise to New York City’s top tier of mayoral hopefuls, Zohran Mamdani has battled opponents’ attacks on his inexperience, his leftward politics and his criticism of Israel’s war in Gaza.

But this week, Mr. Mamdani found himself facing a new attack that was both pointed and illogical, when a Republican city councilwoman from Queens called for him to be deported. (Mr. Mamdani is a U.S. citizen.)

The remark by the councilwoman, Vickie Paladino, who is known for her incendiary social media posts, quickly became a talking point in the Democratic mayoral primary race, just a day before the candidates were to face off in their first debate.

Ms. Paladino recirculated a 2019 social media post from Mr. Mamdani in which he said he couldn’t vote for Senator Bernie Sanders of Vermont for president in 2016 because he was not a citizen at the time. She was incredulous that Mr. Mamdani was being treated seriously as a mayoral candidate.

“Let’s just talk about how insane it is to elect someone to any major office who hasn’t even been a U.S. citizen for 10 years — much less a radical leftist who actually hates everything about the country and is here specifically to undermine everything we’ve ever been about,” Ms. Paladino wrote on X late Monday evening. “Deport.”

Mr. Mamdani, who is polling second behind former Gov. Andrew M. Cuomo in the June 24 primary, soon responded.
