Former New York Mayor Rudy Giuliani told Newsmax on Friday he does not believe current Mayor Zohran Mamdani should appear at ceremonies honoring the 25th anniversary of the Sept. 11 attacks.

Giuliani asserted there is an internal movement of people trying to take over the United States and turn it into an Islamic country. Mamdani is Muslim.

“Why are they fighting about Sharia law in Texas and in Dearborn, Michigan?” Giuliani said on “Finnerty.” “When the Germans came here, they didn’t ask for German law. The Puerto Ricans didn’t ask for Puerto Rican law. The Irish didn’t ask for Irish law.”

“They want to impose a barbaric foreign code on us, given the advances that we’ve made as an Anglo-American country,” Giuliani said. “It’s a disgrace. They’re trying to accomplish by infiltration what they couldn’t accomplish by murderous attack.”

Giuliani also ripped former mayoral candidate Curtis Sliwa for his remarks about family members of 9/11 victims.

“Every once in a while says things I don’t quite understand,” Giuliani said. “If he’s attacking the victims’ families, I don’t know what’s happened to him.

“When I was the mayor, and Bloomberg following me, we just about universally respected the wishes of those families,” Giuliani added. “Because every time we would go to a service and I went to more funerals, than any mayor ever, you had to respect them.

“You can’t imagine going through what they went through, losing your child, losing your husband, losing your wife,” Giuliani continued. “It’s awful [under] any circumstances, but having them attacked by a foreign force, Islamic terrorism, sacrificed that way, you never get over that.”
