Darializa Avila Chevalier, the Democratic Socialists of America, backed candidate for New York's 13th Congressional District, abruptly ended a live radio interview on Election Day after hosts pressed her about deleted social media posts, then defeated five-term incumbent Rep. Adriano Espaillat hours later in what amounted to the biggest Democratic primary upset of the cycle.
The walkout happened at La Mega, a Spanish-language station popular in the heavily Dominican-American district that stretches across parts of Manhattan and the Bronx. Hosts asked Avila Chevalier to address community members troubled by her archived online statements. She declined, removed her headphones, said "Have a beautiful day," and left the studio, Fox News reported.
By the time the polls closed Tuesday evening, none of it mattered, at least not to the voters who handed her the nomination. In a district so reliably Democratic that the primary winner will almost certainly take the seat in November, Avila Chevalier toppled Espaillat, the chairman of the Congressional Hispanic Caucus, who had held the seat since 2017.
Scrutiny of Avila Chevalier's now-deleted social media posts had been building for weeks before the primary. Fox News described the posts as "anti-America" in tone. The specific verbatim text has not been published, and the posts themselves have been scrubbed.
What is known: Avila Chevalier helped lead protests against the Israel-Hamas war at Columbia University and was part of a campus group there that later called for "Death to America." She also made past comments directed at former Vice President Kamala Harris, remarks she acknowledged and apologized for during recent debates.
During the La Mega interview, one host asked her to take the opportunity to "address the Dominican community that may feel bad for the things she has said in the past." Avila Chevalier responded that she felt bad about her past tweets in general but said it was time to unite and "fight for the things that are necessary for the community."
When hosts continued to press, she pushed back. She said she wanted to discuss the "issues that are impacting the residents of New York 13" and insisted she was focused on the people who live in the district. Then she drew the line, as previously covered on this site:
"I am not going to sit here and be yelled at by various people."
With that, she walked out.
The social media controversy is not the only flash point. In a recent interview, Avila Chevalier stated flatly that she believes "all deportations are wrong." In a district where immigration is a daily reality, and where many legal immigrants followed the rules to get here, that position puts her well to the left of even most Democratic voters nationally.
She also drew questions about comments related to Dominican nationalism and the Dominican flag, though the precise content of those remarks has not been detailed publicly. Her pattern has been consistent: delete the post, express general regret, then redirect the conversation to housing, healthcare, or other progressive priorities.
It is a familiar playbook. Acknowledge just enough to get past the question, then pivot. The trouble is that the questions keep finding her.
New York City Mayor Zohran Mamdani endorsed Avila Chevalier and campaigned alongside her at a Get Out the Vote rally at King's Theater on June 18, 2026. Sen. Bernie Sanders appeared at the same event, lending the candidate national progressive star power in a local race.
Mamdani's involvement is part of a broader pattern. The mayor has backed socialist challengers against fellow Democrats across the city, drawing sharp criticism from party leaders who see him undermining incumbents within his own coalition. His willingness to stand behind Avila Chevalier, even as the social media posts surfaced, says something about his priorities.
Mamdani has had his own share of scrutiny. Questions about ethics issues have piled up around the mayor, and his political brand increasingly depends on the success of candidates further to the left than the party mainstream. If Avila Chevalier's past statements become a liability in the general election, however unlikely a Republican upset may be in NY-13, the fallout will land on his doorstep, too.
Adriano Espaillat was no backbencher. He chaired the Congressional Hispanic Caucus, had served five terms, and was a fixture of Dominican-American political life in upper Manhattan and the Bronx. His defeat signals a leftward lurch in a district that was already deep blue.
Espaillat's loss also reflects the power of DSA-aligned organizing in low-turnout primaries. When only the most motivated voters show up, a disciplined progressive operation can overwhelm a complacent incumbent, even one with institutional backing and name recognition built over nearly a decade.
The question now is what kind of congresswoman Avila Chevalier intends to be. Her stated belief that all deportations are wrong, her ties to campus protest movements, and her reflexive hostility when confronted with her own record suggest she will land squarely in the most progressive wing of the House Democratic caucus.
Meanwhile, the broader political turbulence around Mamdani's circle shows no sign of calming. The mayor's allies keep winning primaries, and they keep arriving with baggage that the campaign trail has not fully unpacked.
Several basic facts remain unclear. The exact text of the deleted posts has not been published. The specific campus group at Columbia that called for "Death to America", and Avila Chevalier's precise role in it, has not been fully detailed. The final vote totals and margin of victory in the NY-13 primary have not been reported in available coverage. And Avila Chevalier's campaign has not issued a public statement addressing the walkout or the primary result.
Those gaps matter. Voters in NY-13 deserve to know exactly what their likely next representative said, when she said it, and whether her apologies are genuine or tactical. Deleting posts is not accountability. Walking out of interviews is not transparency.
The pattern around Mamdani and his endorsed candidates is becoming hard to ignore: win first, explain later, or better yet, never explain at all.
When a candidate's best strategy for handling her own words is to delete them and leave the room, voters should ask what else she plans to do behind closed doors once she gets to Washington.
