Darializa Avila Chevalier, the 32-year-old presumptive Democratic congresswoman backed by New York City Mayor Zohran Mamdani, has confirmed she is in a romantic relationship with Ramzi Kassem, the 48-year-old attorney who serves as Mamdani's chief legal counsel and who previously represented Guantanamo Bay detainees linked to al Qaeda, including one man described as a "close associate" of Osama bin Laden.
The relationship, which became official in 2023, ties together three figures at the center of New York's rising socialist left: a congressional candidate, the mayor who endorsed her, and the lawyer who advises him, all bound by shared activism, overlapping professional work, and now personal romance. The Washington Free Beacon reported the details of the arrangement, drawing on a statement Chevalier provided to City & State.
The facts raise pointed questions about political entanglement, and about the network of relationships shaping who gets endorsed, who gets hired, and who gets sent to Congress from New York City.
Chevalier described the relationship in a statement shared with City & State:
"Ramzi Kassem and I met outside an ICE detention facility, both working to free someone unjustly held. Over the years, as we collaborated on different projects, our professional acquaintance became a friendship, which grew into a romantic relationship. I'm deeply grateful for such a loving, supportive partner, he's been a refuge these past few years."
She did not name the facility or the person they were working to free. What she did confirm is that the relationship grew out of shared professional activism, activism that has taken both of them deep into anti-enforcement, anti-Israel, and anti-border-security advocacy.
Kassem, a CUNY law professor and Columbia College and Columbia Law School alumnus, helped Chevalier with a research paper that analyzed what was described as the racism and Islamophobia of a Customs & Border Protection anti-terror unit. The couple became official in 2023, the same period in which their professional collaboration was ongoing.
Mamdani then appointed Kassem as his chief counsel in January. A spokeswoman for the mayor told City & State that Mamdani had been "aware of their relationship for some time" and discussed Chevalier's congressional campaign with Kassem before endorsing her.
That sequence matters. The mayor's top legal adviser is dating the candidate the mayor endorsed for Congress, and the mayor discussed the endorsement with that adviser beforehand. In any professional setting outside politics, this would be called a conflict of interest. In New York's Democratic Socialists of America orbit, it appears to be standard operating procedure.
Kassem's legal career has centered on representing Guantanamo Bay detainees. Two of his most notable clients stand out.
Ahmed al-Darbi was convicted in 2017 for the bombing of a French oil tanker, a case documented in a U.S. Department of Defense sentencing announcement. Shaker Aamer, another Kassem client, was described by the Washington Post as a "close associate of Osama bin Laden" who fought in the 2001 Battle of Tora Bora, the same battle in which U.S. forces stormed an al Qaeda complex where bin Laden was hiding.
Kassem also defended Mahmoud Khalil, a Syrian-born Columbia graduate student and organizer with Columbia University Apartheid Divest, after the Trump administration revoked Khalil's green card.
Defense attorneys represent unpopular clients. That is how the legal system works. But Kassem's career is not merely a matter of courtroom duty. His activism extends well beyond legal representation. While at Columbia, he lobbied to rename a sandwich called the "Israeli wrap" in the student dining hall. His professional and personal trajectory reflects a sustained political project, one that now runs directly through City Hall and into a congressional campaign.
Both Kassem and Chevalier were deeply involved in anti-Israel campus activism at Columbia University. Chevalier cofounded Columbia University Apartheid Divest, known as CUAD, a group that has openly supported what was described as "armed resistance" by Hamas.
On March 1, 2026, CUAD posted a statement declaring "Death to America" after the United States launched military action against Iran. That is the organization Chevalier helped build. And Mahmoud Khalil, the man Kassem defended after his green card was revoked, was a CUAD organizer.
The connections form a tight loop: Chevalier cofounded the group. Kassem defended its organizer. Both worked together on immigration and border enforcement issues. They began dating. Mamdani hired Kassem. Mamdani endorsed Chevalier. And now Chevalier is described as a presumptive Democratic congresswoman.
None of these facts are hidden. They are simply arranged in a way that makes the network visible.
Kassem attended Columbia Law School on a fellowship funded by Paul Soros. He went from campus activism to Guantanamo defense work to a CUNY law professorship to the mayor's chief counsel position. Chevalier went from cofounding CUAD to graduate school to a congressional campaign backed by the mayor whose top lawyer she is dating.
The Free Beacon drew a comparison to Kamala Harris, who dated California Democratic kingmaker Willie Brown before launching her first political campaign for San Francisco district attorney. The parallel is imperfect, Harris and Brown's relationship predated her candidacy, while Chevalier and Kassem's relationship overlaps with active political endorsement and professional entanglement. But the underlying pattern is familiar: personal relationships that double as political infrastructure.
The Free Beacon characterized the arrangement as evidence that the Democratic Socialists of America are "embracing the tactics of establishment figures in the Democratic Party, using romantic relationships to climb the political ladder." That framing is the publication's own interpretation. But the underlying facts, the timeline, the endorsement, the adviser-candidate relationship, speak clearly enough on their own.
Several questions hang over this story. What congressional district is Chevalier running in, and on what basis is she described as the "presumptive" winner? Did Kassem make any statement about the relationship or about his legal work on behalf of al Qaeda-linked detainees? What are the ethics rules, if any, governing a mayoral adviser's romantic relationship with a candidate the mayor has endorsed?
And perhaps most pointedly: did Kassem's position as Mamdani's chief counsel play any role, direct or indirect, in the mayor's decision to endorse Chevalier? The mayor's spokeswoman said Mamdani discussed the campaign with Kassem before endorsing. That disclosure was apparently meant to demonstrate transparency. It does the opposite. It confirms that the man dating the candidate had the mayor's ear on the endorsement question.
In a functioning political culture, that admission would trigger scrutiny. In New York's progressive ecosystem, it barely registers.
The individual facts here are not, on their own, disqualifying. Lawyers represent controversial clients. Activists date other activists. Politicians endorse allies. But when those threads all run through the same three people, and when the result is a congressional seat, a City Hall appointment, and a mayoral endorsement, the arrangement deserves more than a shrug.
Chevalier cofounded a group that declared "Death to America." Her boyfriend represented a man described as a close associate of bin Laden and another convicted of bombing an oil tanker. That boyfriend now serves as the top legal adviser to the mayor who endorsed her for Congress, after the mayor discussed the endorsement with him.
Voters in New York deserve to know exactly what kind of political network is being built with their representation. The people involved have been candid enough to confirm the relationships. The question is whether anyone in the city's political class will bother to ask what those relationships mean for accountability, independence, and the public interest.
When the romantic partners, the political endorsers, and the legal advisers are all the same people, the word for that isn't "love." It's "machine."
