Fresh blow for Musk's DOGE as it loses power to award $500B in federal funds
The US DOGE Service, the repurposed government agency tasked with carrying out Elon Musk 's Department of Government Efficiency agenda to cut a trillion dollars in federal spending, has reportedly lost access to a key government website responsible for distributing roughly $500 billion in annual awards, the latest blow to the initiative after Musk's acrimonious split from the Trump administration earlier this month. Earlier this year, DOGE reportedly assumed effective control of a clearinghouse for federal funding opportunities, requiring new proposals to be sent to a DOGE-controlled mailbox for review before being posted. In the ensuing months since the April policy change, grant opportunities reportedly piled up inside the mailbox, leaving funds at risk of going unspent before the end of the government fiscal year at the end of September. On Thursday, federal officials were instructed to stop running grant proposals through DOGE, The Washington Post reports. 'Robust controls remain in place, with DOGE personnel embedded at each agency, assisting secretaries' offices in reviewing grants daily,' the White House said in a statement about the report. 'Agency secretaries and senior advisors will continue to implement and leverage the controls initially established by DOGE to reduce waste, fraud, and abuse, retaining full agency discretion to determine the appropriate flow of funds at the project level.' The reported process change is the latest hurdle for DOGE. The effort, whose figures have repeatedly been shown to be filled with errors and omissions, appears to have fallen short of Musk's bold promises to rapidly cut major portions of federal spending, with some estimates pegging the true figure of savings achieved at about $180 billion, compared to Musk's goal of some $1 trillion. Numerous DOGE efforts have been paused or shot down in court, and federal agencies are scrambling to hire back many of the employees laid off in Musk's slash-and-burn revamp of federal spending. Still, even with Musk out, the administration remains committed to achieving some major reductions, including a DOGE-style clawback of $9.4 billion in cuts to foreign aid and pubic media spending that's already passed the House. Russell Vought, a major force behind the arch-conservative Project 2025 police blueprint and current director of the Office of Management and Budget, has said DOGE's work will continue apace even without Musk. "Many DOGE employees and [full-time employees] are at the agencies, working almost as in-house consultants as a part of the agency's leadership," he testified this month. "And I think, you know, the leadership of DOGE is now much more decentralized."

Mark Zuckerberg's secret list of top AI talent to poach has tech world atwitter
Mark Zuckerberg reportedly spent months putting together a list of the top AI engineers and researchers across the globe, preparing to offer potential recruits lucrative compensation packages in Meta's attempt to poach AI talent from key competitors. Silicon Valley has been talking for weeks about the Meta CEO's quest to attract top AI talent, including by offering pay packages worth up to $100m. Zuckerberg has personally reached out to desired candidates, according to the Wall Street Journal. Meta, which owns Facebook, Instagram and WhatsApp, has been competing in the search for AI dominance with rivals like OpenAI, Google, Microsoft and Amazon, which have invested billions of dollars into AI research and product development. Last month, questions were raised about the direction of Meta's AI development after it delayed the scheduled rollout of Behemoth, its flagship AI model. Earlier this month, Meta paid $14bn for a stake in Scale AI and is putting its founder, 28-year-old Alexandr Wang, in charge of its 'superintelligence team' – an internal lab that would focus on Meta's efforts to develop a hypothetical AI system that is smarter than humans. Last year, Google bought out the shareholders in a chatbot service that allows users to have personal conversations with different AI personas, for $2.7bn. People on 'the list', as Zuckerberg's slate is known around Silicon Valley, include recent graduates from top PhD programs at schools like the University of California at Berkeley and Carnegie Mellon. Many are currently employed by Meta's AI competitors, including OpenAI and Google's DeepMind project, and have traded notes with each other on Meta's recruiting efforts. A recruit who has personally spoken to Zuckerberg said that his goal appears to be a 'transfusion from the country's top AI labs'. A WhatsApp group chat called 'Recruiting Party' was formed for Zuckerberg and at least two other senior Meta executives to talk through potential hires. The Meta CEO has been trying to personally find candidates by looking through research papers, according to the Wall Street Journal. Zuckerberg's hands-on recruiting efforts have drawn the ire of OpenAI chief executive Sam Altman, who called the rumored signing bonuses and compensation packages on offer 'crazy'. 'I'm really happy that, at least so far, none of our best people have decided to take them up on that,' Altman said during an appearance on the Uncapped podcast, which is hosted by his brother Jack. 'I think the strategy of a ton of upfront, guaranteed comp, and that being the reason you tell someone to join, like really the degree to which they're focusing on that and not the work and not the mission, I don't think that's going to set up a great culture.'

Mark Zuckerberg's charity backing away from DEI and political spending after Trump criticisms and staff tensions: report
The Chan Zuckerberg Initiative, the multi-billion-dollar philanthropy led by Meta CEO Mark Zuckerberg and his wife Dr. Priscilla Chan, is reportedly moving away from political spending, following criticism from Republicans and internal tensions with liberal staff members. The initiative, founded in 2015, always invested in a combination of social and scientific causes, but has recently rebranded as 'science-first,' and has ended internal diversity programs, housing initiatives, and diversity-focused funding for scientists. This spring, a school for low-income students that Chan founded also closed. The shift, which has also included an overall slowdown in spending, with $336 million in grants, less than half the group's average, came after a series of bruising encounters with politics, The New York Times reports. Chan and Zuckerberg were reportedly frustrated after getting criticism from Trump and his allies for efforts like donating $400 million to nonpartisan election infrastructure in the 2020 race, an effort MAGA derided as 'Zuckerberg bucks.' Trump, for his part, threatened the Meta boss with 'life in prison' during the 2024 campaign if he intervened in the election. Political fatigue reportedly began even earlier, according to the Times, with Zuckerberg growing frustrated with criticisms from liberal staff members at the philanthropy in the wake of the 2020 racial justice protests. The Independent has contacted the Chan Zuckerberg Initiative for comment. The organization has explained the changes as a combination of new strategy and a shifting political landscape. In a June letter, Chan, a pediatrician, emphasized the group's long-running commitment to curing disease, a cause she became attached to as a doctor in San Francisco. 'It was there that I saw the limits of medicine and science up close, working with children with rare diseases,' she wrote in a June blog post. 'For those families, expanding the limits of what we know — advancing basic science research — is their only hope for a better life for their child. In a February post, the initiative explained its decision to cut its DEI teams as a response to the ' shifting regulatory and legal landscape.' In recent years, the Supreme Court has struck down race-based affirmative action in higher education admissions, and the Trump administration has sought to end DEI in both the public and private sector. At the same time, as the Republican has returned to power, Meta has repositioned itself with moves seen by some as an attempt to remain in the administration's good graces, including ending diversity programs, eliminating fact-checkers, putting Trump ally Dana White on the Meta board, and attending the president's inauguration earlier this year. Shortly after Trump was elected, Zuckerberg was spotted at Trump's Mar-a-Lago estate, where senior White House official Stephen Miller said the tech billionaire had 'been very clear about his desire to be a supporter of and a participant in this change that we're seeing all around America, all around the world, with this reform movement that Donald Trump is leading.'
