Have an account? President Donald Trump says he has no desire to repair his relationship with Elon Musk. He also said Musk would face "serious consequences" if he funds Democrats. Meanwhile, Musk deleted some of his most incendiary X posts on Saturday. It seems Elon Musk won't be President Donald Trump's "first buddy" again anytime soon.Trump told NBC News on Saturday that he has no plans to repair his relationship with Musk after it imploded this week. When asked if their relationship is done, Trump said, simply, "I would assume so, yeah."Trump said he doesn't intend to speak with Musk and said the tech billionaire was "disrespectful to the office of the President.""I think it's a very bad thing, because he's very disrespectful. You could not disrespect the office of the President," Trump said.The epic and very public fallout began after Musk criticized Trump's tax bill, which the president calls his "One Big Beautiful Bill."During Thursday's dramatic exchange, which took place mostly on the social media networks each billionaire owns, Trump threatened to terminate Musk's government contracts and subsidies. Musk shot back that Trump was in the so-called "Epstein files" in a now-deleted post.In the NBC interview on Saturday, Trump warned Musk against funding Democratic candidates running against GOP members voting in favor of the bill, saying there will be "serious consequences.""If he does, he'll have to pay the consequences for that," Trump said. "He'll have to pay very serious consequences if he does that."Last month, Musk said he would spend "a lot less" on political campaigns in the future. He spent hundreds of millions in support of Trump in 2024."If I see a reason to do political spending in the future, I will do it," Musk said at the Qatar Economic Forum last month. "I do not currently see a reason."Trump's remarks on Saturday came after Musk deleted some X posts from his account. He deleted the post referencing the Epstein files and a video he re-posted that appeared to show Trump partying with Epstein in the 1990s. Musk also deleted an X post in which he called a Trump comment an "obvious lie" and another post saying SpaceX would decommission its Dragon spacecraft "immediately."White House press secretary Karoline Leavitt told Business Insider that passing the tax bill is the president's priority."President Trump and the entire Administration will continue the important mission of cutting waste, fraud, and abuse from our federal government on behalf of taxpayers, and the passage of the One Big Beautiful Bill is critical to helping accomplish that mission," Leavitt said in a statement.Representatives for Musk did not respond to a request for comment from BI.The repercussions from Musk and Trump's dispute were swift, affecting the price of Tesla stock and Dogecoin. A senior White House official told BI that Trump is now considering selling his Tesla.On Saturday, Vice President JD Vance said it was a "huge mistake" for Musk to "go after the president" during the newest episode of "This Past Weekend w/ Theo Von.""I'm not saying he has to agree with the bill or agree with everything that I'm saying," Vance said. "I just think it's a huge mistake for the world's wealthiest man, I think one of the most transformational entrepreneurs ever — that's Elon — to be at this war with the world's most powerful man."During the interview, Vance said he thinks everything will be fine between the pair if Musk "chills out a little bit.""Hopefully Elon figures it out and comes back into the fold," Vance said, adding that Trump had been a "little frustrated" with Musk's recent criticisms."But I think he's been very restrained because the president doesn't think that he needs to be in a blood feud with Elon Musk, and I actually think if Elon chilled out a little bit, everything would be fine," Vance said.Musk responded to Vance's comment on X on Saturday, writing, simply, "Cool."

June 5, 20254 min readThe Trump-Musk Fight Could Have Huge Consequences for U.S. Space ProgramsA vitriolic war of words between President Donald Trump and SpaceX CEO Elon Musk could have profound repercussions for the nation’s civil and military space programsBy Lee Billings edited by Dean VisserElon Musk (left) and President Donald Trump (right) seemed to be on good terms during a press briefing in the Oval Office at the White House on May 30, 2025, but the event proved to be the calm before a social media storm. Kevin Dietsch/Getty ImagesFor several hours yesterday, an explosively escalating social media confrontation between arguably the world’s richest man, Elon Musk, and the world’s most powerful, President Donald Trump, shook U.S. spaceflight to its core.The pair had been bosom-buddy allies ever since Musk’s fateful endorsement of Trump last July—an event that helped propel Trump to an electoral victory and his second presidential term. But on May 28 Musk announced his departure from his official role overseeing the U.S. DOGE Service. And on May 31 the White House announced that it was withdrawing Trump’s nomination of Musk’s close associate Jared Isaacman to lead NASA. Musk abruptly went on the attack against the Trump administration, criticizing the budget-busting One Big Beautiful Bill Act, now navigating through Congress, as “a disgusting abomination.”Things got worse from there as the blowup descended deeper into threats and insults. On June 5 Trump suggested on his own social-media platform, Truth Social, that he could terminate U.S. government contracts with Musk’s companies, such as SpaceX and Tesla. Less than an hour later, the conflict suddenly grew more personal, with Musk taking to X, the social media platform he owns, to accuse Trump—without evidence—of being incriminated by as-yet-unreleased government documents related to the illegal activities of convicted sex offender Jeffrey Epstein.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

It’s the main way NASA’s astronauts get to and from the International Space Station (ISS) and also a key component of a contract between NASA and SpaceX to safely deorbit the ISS in 2031. If Dragon were to be no longer be available, NASA would, in the near term, have to rely on either Russian Soyuz vehicles or on Boeing’s glitch-plagued Starliner spacecraft for its crew transport—and the space agency’s plans for deorbiting the ISS would essentially go back to the drawing board. More broadly, NASA uses SpaceX rockets to launch many of its science missions, and the company is contracted to ferry astronauts to and from the surface of the moon as part of the space agency’s Artemis III mission.Trump’s and Musk’s retaliatory tit for tat also raises the disconcerting possibility of disrupting other SpaceX-centric parts of U.S. space plans, many of which are seen as critical for national security. Thanks to its wildly successful reusable Falcon 9 and Falcon Heavy rockets, the company presently provides the vast majority of space launches for the Department of Defense. And SpaceX’s constellation of more than 7,000 Starlink communications satellites has become vitally important to war fighters in the ongoing conflict between Russia and U.S.-allied Ukraine. SpaceX is also contracted to build a massive constellation of spy satellites for the DOD and is considered a leading candidate for launching space-based interceptors envisioned as part of Trump’s “Golden Dome” missile-defense plan.Among the avalanche of reactions to the incendiary spectacle unfolding in real time, one of the most extreme was from Trump’s influential former adviser Steve Bannon, who called on the president to seize and nationalize SpaceX. And in an interview with the New York Times, Bannon, without evidence, accused Musk, a naturalized U.S. citizen, of being an “illegal alien” who “should be deported from the country immediately.”NASA, for its part, attempted to stay above the fray via a carefully worded late-afternoon statement from the space agency’s press secretary Bethany Stevens: “NASA will continue to execute upon the President’s vision for the future of space,” Stevens wrote. “We will continue to work with our industry partners to ensure the President’s objectives in space are met.”The response from the stock market was, in its own way, much less muted. SpaceX is not a publicly traded company. But Musk’s electric car company Tesla is. And it experienced a massive sell-off at the end of June 5’s trading day: Tesla’s share price fell down by 14 percent, losing the company a whopping $152 billion of its market value.Today a rumored détente phone conversation between the two men has apparently been called off, and Trump has reportedly said he now intends to sell the Tesla he purchased in March in what was then a gesture of support for Musk. But there are some signs the rift may yet heal: Musk has yet to be deported; SpaceX has not been shut down; Tesla’s stock price is surging back from its momentary heavy losses; and it seems NASA astronauts won’t be stranded on Earth or on the ISS for the time being.Even so, the entire sordid episode—and the possibility of further messy clashes between Trump and Musk unfolding in public—highlights a fundamental vulnerability at the heart of the nation’s deep reliance on SpaceX for access to space. Outsourcing huge swaths of civil and military space programs to a disruptively innovative private company effectively controlled by a single individual certainly has its rewards—but no shortage of risks, too.

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Manus has kick-started an AI agent boom in China Last year, China saw a boom in foundation models, the do-everything large language models that underpin the AI revolution. This year, the focus has shifted to AI agents—systems that are less about responding to users’ queries and more about autonomously accomplishing things for them.There are now a host of Chinese startups building these general-purpose digital tools, which can answer emails, browse the internet to plan vacations, and even design an interactive website. Many of these have emerged in just the last two months, following in the footsteps of Manus—a general AI agent that sparked weeks of social media frenzy for invite codes after its limited-release launch in early March.As the race to define what a useful AI agent looks like unfolds, a mix of ambitious startups and entrenched tech giants are now testing how these tools might actually work in practice—and for whom. Read the full story. —Caiwei Chen Inside the race to find GPS alternatives Later this month, an inconspicuous 150-kilogram satellite is set to launch into space aboard the SpaceX Transporter 14 mission. Once in orbit, it will test super-accurate next-generation satnav technology designed to make up for the shortcomings of the US Global Positioning System (GPS). Despite the system’s indispensable nature, the GPS signal is easily suppressed or disrupted by everything from space weather to 5G cell towers to phone-size jammers worth a few tens of dollars. The problem has been whispered about among experts for years, but it has really come to the fore in the last three years, since Russia invaded Ukraine.Now, startup Xona Space Systems wants to create a space-based system that would do what GPS does but better. Read the full story. —Tereza Pultarova Why doctors should look for ways to prescribe hope —Jessica Hamzelou This week, I’ve been thinking about the powerful connection between mind and body. Some new research suggests that people with heart conditions have better outcomes when they are more hopeful and optimistic. Hopelessness, on the other hand, is associated with a significantly higher risk of death. The findings build upon decades of fascinating research into the phenomenon of the placebo effect. Our beliefs and expectations about a medicine (or a sham treatment) can change the way it works. The placebo effect’s “evil twin,” the nocebo effect, is just as powerful—negative thinking has been linked to real symptoms. Researchers are still trying to understand the connection between body and mind, and how our thoughts can influence our physiology. In the meantime, many are developing ways to harness it in hospital settings. Is it possible for a doctor to prescribe hope? Read the full story.
