CNN host Kaitlan Collins interrupted a live interview with congressional candidate Brad Lander to inform him that he had just toppled incumbent Dan Goldman in a bruising Democratic primary.

Lander, the former New York City comptroller, had been speaking to Collins on Tuesday night when she paused the discussion to make the projection in NYC's 10th Congressional District.

'We came on the air just a couple of minutes ago as the numbers were still coming in,' Collins told Lander. 

'In your race, I'm gonna do something a little unusual here, so I want you to bear with me... Not many candidates are on CNN when they hear this music.' 

Collins then announced CNN's projection that Lander would defeat Goldman, the incumbent Democrat, in the primary for the Manhattan-and-Brooklyn district.

'Sir, obviously, since we have you here live on air, as we are making this call, what is your first reaction to this?' Collins asked.

Lander appeared caught off guard by the timing.

'Well, thank you. First of all, obviously I'm thrilled,' he replied. 'I did not expect to be on air when the race was called.'

Lander said he relished the democratic process and promised to represent the concerns he heard from voters during the campaign.

‘I love election day. I like the voters get to go out and cast their ballots and say, here’s who we want to represent us. These are the fights that matter to us,’ he said.

‘All I can say is I promise to go out every single day and fight for my constituents and the values that they have because we need a country that stands up for working people,' he said. 

‘I’ll be fighting for a city everyone can afford and where everyone is welcome,’ Lander added. ‘And I’m really honored to be on your show tonight.’

Lander and Mamdani had previously faced each other in the 2025 Democratic mayoral primary before cross-endorsing in an effort to prevent former Governor Andrew Cuomo from winning the nomination. 

The call was a major defeat for Goldman, who had represented the district since 2022 and was seeking to hold onto a seat covering Lower Manhattan and parts of western Brooklyn.

Lander’s victory was also an emphatic show of strength for New York City Mayor Zohran Mamdani, who backed his fellow progressive in the contest.

Mamdani’s endorsements were closely watched on Tuesday as the mayor sought to push New York’s congressional delegation further left.

Lander was one of three Mamdani-backed candidates who prevailed in high-profile Democratic primaries.

NBC News called the race less than 10 minutes after polls closed, with Lander quickly building a commanding early lead. CNN subsequently made its own projection while he was being interviewed by Collins.

Goldman’s position on Israel and the war in Gaza became a major flashpoint during the campaign.

The congressman, who is Jewish, had not endorsed Mamdani during last year’s mayoral contest, citing concerns over antisemitism. 

Lander, who is also Jewish, made Goldman’s support for Israel a key dividing line in the race.

Goldman had previously pushed back against accusations from critics who branded him a ‘genocide enabler’ over his backing of Israel’s military campaign in Gaza following Hamas’s October 7 attack.

‘What is going on in the Middle East is horrific. And the idea of accusing someone who you don’t know of supporting a genocide - I mean, it’s crazy,’ Goldman told CNN.

‘Now, I may disagree as to whether or not there’s a genocide, but come on. We’re better than this.’

Goldman was first elected to Congress in 2022 after a career as a federal prosecutor. 

He is also an heir to the Levi Strauss fortune and served as lead counsel during Donald Trump’s first impeachment inquiry in 2019.
