The other Rudy is a 67-year-old retired public school principal serving students with special needs in Brooklyn. Like their cousin, both Rudy and Catherine are registered Republicans. Catherine even worked for the other Giuliani during his tenure in City Hall.

Adams, of course, is a Democrat, but the former police officer has been embraced and supported by many Republicans – including, to a point, former Mayor Giulani, who all but endorsed Adams ahead of the 2021 primary. Asked by CBS New York who the best candidate in the Democratic field was, Giuliani said “at least Adams talks about reducing crime … There’s no question that Adams gives us some hope.”

Adams hasn’t been so warm in response. He immediately rejected Giuliani’s support in 2021, and, last year, said his predecessor should be prosecuted for false reporting, after Giuliani claimed somebody patting him on the back was an assault.

Adams has been steadily raising money for his 2025 reelection campaign – reporting $1.3 million as of Jan. 2023 – giving him a huge head start on any candidate who may want to challenge him. Because Adams is taking part in the public matching funds program, the maximum any individual can donate to him is $2,100. But as a city lobbyist, Catherine Giuliani is limited to the lower “doing business” limit of $400. For guests at the fundraiser, however, “the suggested contribution is $1000, but we will accept donations of $500,” Catherine Giuliani wrote in an emailed invitation.
