Bill Maher denounced socialist New York mayoral frontrunner Zohran Mamdani for “campaigning with a terrorist,” and called out the Democrat’s refusal to renounce his Ugandan citizenship in a fiery clash with CNN political commentator Kate Bedingfield on his “Real Time” show.

The comedian and TV host, 69, was defending former New York Gov. Andrew Cuomo, following the liberal backlash over his comments about Mamdani and 9/11.

Cuomo was criticized for seemingly agreeing with a conservative radio host who said Mamdani would have cheered if he were mayor during the 9/11 attacks, remarks that drew the ire of Bedingfield.

“I’m talking about what Cuomo’s doing, suggesting that Mamdani couldn’t be a leader in a terror situation if he were mayor of New York,” Bedingfield said during Friday’s show.

“Well, he [Mamdani] did campaign with a terrorist this week,” Maher said in response, before doubling down on his point.

“Well, he campaigned this week with a guy who was an unindicted co-conspirator in the 1993 World Trade Center bombing and served as a character witness for Omar Abdelrahman, the terrorist who organized it,” he said, referring to an image of Mamdani alongside Siraj Wahhaj.

“I just don’t know if this is a great look for the party,” he added.

Maher and Bedingfield also clashed over Mamdani’s dual Ugandan citizenship.

“You make it sound like he’s a little more mainstream than I think he is. I mean, the issue now that Andrew Cuomo is bringing up in New York is that he is a Ugandan citizen. Uganda’s a country where they kill homosexuals,” Maher said.

“So somebody who is a dual citizen can’t be mayor of New York or?” retorted Bedingfield, triggering a sharp response from Maher.

“If I was a dual citizen with a country whose policy, government policy, was we kill homosexuals. Yeah, I would renounce that citizenship,” he said.

Maher also warned that Mamdani’s victory could have major implications for the Democrats’ chances nationally.

“I think the whole Democratic Party in the country is on the ballot, and the whole country will be looking at this race to see which way are the Democrats going to go,” he said.

Admitting that Cuomo wasn’t inspirational or exciting, he said that the former Gov. was “kind of normal,” prompting Bedingfield to insist Mamdani would galvanize the Democrats.

“I think that if Mamdani wins with a coalition of voters who have been not-all-that excited about the Democratic Party over the last few years, I think that’s a good thing for the Democrats,” she said, adding that he could also help the more centrist Dems.

“I think if you’re in a purple district, say you disagree with some of the things that he does and use that to establish your independent cred,” she said.

Mamdani addressed criticism of the photo of him with Wahhaj during a “Cost of Living” soccer tournament in New York.

“The same imam met with Mayor [Michael] Bloomberg, met with Mayor [Bill] de Blasio, campaigned alongside Eric Adams, and the only time it became an issue of national attention was when I met with him,” Mamdani said, according to CBS New York.

“And that’s because of the fact of my faith and because I’m on the precipice of winning this election,” he added.

Mamdani’s campaign did not respond immediately to requests for comment.
