They Were Once Again Very Wrong X: Jasper Nathaniel / @infinite_jaz : Shaun Maguire posted a video rant accusing a queer pro-Palestine Brown student of being the shooter then quietly deleted it after Brown denied the claim. He's making strong late-stage push for Biggest Disgrace of 2025. [image] Shaun Maguire / @shaunmmaguire : Update: I'm not 100% sure he's Jewish. Before making that claim I: 1) heard it from 2 friends with ties to MIT 2) asked Gemini (SS) 3) another friend sent me this tweet from him criticizing Hamas and Islamism But there's a chance he's not Jewish, but definitely pro Israel [image] Jasper Nathaniel / @infinite_jaz : Here is @shaunmmaguire's now-deleted live video, in which he claims there is “very strong evidence” that Mustapha Kharbouch, a Palestinian Brown student, “likely” committed the murders of two Brown students. He treats Brown removing pages about Kharbouch as evidence of guilt, [video] Franklin Leonard / @franklinleonard : Tough break for Shaun Maguire: Tried to blame a Palestinian and it ended up being a physics guy of European descent, just like him. It was all so predictable. [image] Dan Primack / @danprimack : Those who shared photos of a current Brown student, suggesting he was the shooter, should take a long look in the mirror tonight. “Why did they delete the page?” Because of people like you.

He is now performing serial Dreyfus Affairs on weak Palestinians. Sam Biddle / @samfbiddle : There was a time, not that long ago, when having an openly racist partner at a blue chip venture capital firm falsely accusing someone of murder would have been a big problem for that firm.

There are people on this platform, some who are well known to many others, who are given a free hand to spout lies and destroy other peoples' lives, esp of those with Muslim and Arab sounding names. Such people should be held accountable. Bluesky: Bruno J. Navarro / @brunojnavarro : Neither Shaun Maguire, nor Sequoia, responded to interview requests for this story.

Context & Ripple Effects
This is the latest escalation in an already public dispute over whether Sequoia should bear institutional consequences for Maguire’s political speech. A founder-and-investor letter urging Sequoia to act followed his earlier remarks about Zohran Mamdani.
Subsequent coverage described how internal leadership defended distinctions in Maguire’s rhetoric as the firm was drawn into culture-war controversies. The new episode tests whether that prior defense of Maguire can contain reputational damage when a named student is wrongly implicated in a violent event.
First-order effects
- Mustapha Kharbouch faces the immediate reputational and personal harm of a false public accusation, even after the post’s deletion and official denials.
- Sequoia again becomes associated with a partner’s conduct on X, increasing scrutiny of its leadership’s willingness to set boundaries around public statements.
Second-order effects
- Founders, limited partners, and portfolio-company employees who had already pressed Sequoia to respond have a concrete new incident against which to judge the firm’s governance and culture.
- The episode highlights how a high-reach account can amplify an unverified claim faster than corrections can repair its effects, raising the stakes for platforms and prominent users during breaking-news events.
Third-order effects
- If repeated controversies produce no visible institutional response, professional firms may find that partners’ personal social-media behavior is treated by stakeholders as firm-level risk rather than private expression.
- The broader pressure point is reputational governance: organizations will increasingly need credible ways to distinguish protected personal commentary from conduct that exposes identifiable people to harm.
The trend: Prominent investors’ social-media posts are becoming a governance and reputation issue for their firms, particularly when platform reach turns unverified claims into real-world exposure.
