An ally of New York City mayor Zohran Mamdani learned live on CNN that he had won his Democrat primary against an incumbent Congressman. Former city comptroller Brad Lander quickly racked up more than 60 per cent of the vote against Rep. Dan Goldman, who has faced a backlash over his support for Israel. Lander learned the race had been officially called while live on cable news. “Not many candidates are on CNN when they hear this music,” host Collins said. “But we do have breaking news, and we can now project that Brad Lander will defeat the incumbent congressman, Dan Goldman, in the Democratic primary for New York’s 10th congressional district.”
