To honor the end of Elon Musk's "incredible" government service, President Trump presented his friend, adviser and billionaire benefactor with a golden key to the White House.

• Six days later, Musk lit the place on fire, Axios' Zachary Basu writes.

Why it matters: The most powerful civilian ever has effectively declared war on the president of the United States, incinerating their relationship — at least for now — in one of history's most extraordinary political meltdowns.

• The long-predicted rupture built over months, but exploded in hours — unfolding in real time in the Oval Office, on Truth Social and above all, on X.
• The consequences were tectonic, shaking the foundations of a MAGA-tech coalition that has mapped out grand ambitions for Trump's second term.

🔎 Zoom in: Tensions have simmered all week over Musk's scathing criticism of Trump's budget-busting tax bill, which is projected to add trillions to the national debt.

• Yesterday, Trump claimed the Tesla CEO was lashing out over the bill's rollback of electric vehicle credits — and suggested he was suffering from "Trump Derangement Syndrome."

Musk responded by committing what can only be described as an unforgivable sin in Trumpworld: claiming credit for the president's 2024 election victory and arguing that his political power would far outlast Trump's.

Trump fired back by threatening to terminate Musk's billions of dollars in government subsidies and contracts, and declaring that his former adviser had gone "crazy."

• Over the next few hours, Musk would call for Trump's impeachment, claim the president is implicated in unreleased Jeffrey Epstein files, and float the creation of a new political party.
• He also announced that SpaceX would "begin decommissioning its Dragon spacecraft immediately" — a move that would disrupt NASA operations and sever a core link between his empire and the federal government.

Between the lines: Musk later walked back that threat and opened the door to a thaw with Trump. He responded positively ("You're not wrong") to a plea by financier Bill Ackman that they make peace.

• White House aides scheduled a call with Musk for today, Politico reported.

The episode underscored the extraordinary leverage the billionaire holds over critical government functions — and how easily that power can be politicized.

🖼️ The big picture: Musk, who spent nearly $300 million to support Trump and GOP candidates in 2024, views the swelling deficit as an existential threat, and has promised to target any Republican who votes for the bill.

• GOP lawmakers, many of whom have spent years terrified by the prospect of a Trump-backed primary threat, are now praying the president's endorsement is worth more than Musk's war chest.

Shortly after President Trump unexpectedly withdrew Elon Musk's pick to lead NASA last weekend, one name quickly surfaced as a major force behind the surprise decision: White House personnel director Sergio Gor, Axios' Marc Caputo, Alex Isenstadt and Stef W. Kight write.

• Why it matters: Trump acknowledged yesterday that canceling Jared Isaacman's NASA nomination had "upset" Musk, who's close to Isaacman.

Some presidential advisers were angry at Gor, who had a tense relationship with Musk. Some Senate Republicans also said Gor helped undermine the NASA nomination to settle a score with Musk, who'd been critical of Gor.

• On the "All-In" podcast," Isaacman said he believes his fate was linked to Musk's deteriorating standing in the White House and "an influential adviser coming in and saying [to Trump]: 'Look, here's the facts and I think we should kill this guy.'''
• Gor declined to comment. White House communications director Steven Cheung said Gor "is a vital member of the team and he has helped President Trump put together an administration that is second to none."

🔬 Zoom in: Gor is one of the most influential Trump advisers in the White House, and co-founded Winning Team Publishing with Don Jr. The imprint publishes books by Trump and his allies, and put much-needed cash in Trump's pocket during his isolation after the Jan. 6 riot at the Capitol.

• Gor, a frequent presence at Mar-a-Lago, has a close relationship with former Marvel executive Ike Perlmutter, one of Trump's closest friends and a major donor.
• Gor was a top fundraising official on Trump's 2020 re-election campaign, and founded a pro-Trump super PAC during the 2024 campaign that spent nearly $72 million.

📁 Behind the scenes: Gor has told others that GOP senators triggered Isaacman's demise, including Sen. Ted Cruz (R-Texas), chair of the Committee on Commerce, Science and Transportation, which oversees NASA.

• Cruz raised objections in December — when Musk persuaded Trump to nominate Isaacman — including past donations to Democrats.
• Cruz's concerns were allayed, and the committee he chairs approved Isaacman's nomination by a big margin in April, with Cruz voting in support.

Gor recently "spun up the president by just constantly mentioning the donations," a Trump adviser said.

• On May 30, before a joint press conference with Musk to announce his departure from the White House, Gor dropped off a background file on Isaacman at the Oval Office. Musk later entered the room and Trump asked him about Isaacman.

"This guy gave to Democrats," Trump said to Musk, according to a person familiar with the meeting.

• "It's not like Elon really defended him," the source said. "He said: 'He's really competent. But yeah, he gave to Democrats.'"

The breakdown of President Trump's relationship with Elon Musk yesterday cost both men significant sums of money — about $21 billion combined, Axios' Ben Berkowitz writes.

• Why it matters: Both have vast business empires. But they each have one public company that investors dumped as the social media war spiraled into personal attacks.

🧮 By the numbers: Tesla shares dropped 14.3%, costing Musk just under $20 billion.

• The 8% decline in Trump Media & Technology Group cost the president about $202 million.
• The bigger hit to Trump's bottom line was the roughly 10% decline of his Official Trump meme coin, potentially costing him nearly $900 million.

As the nation remembers D-Day's 81st anniversary today, a dwindling number of World War II veterans remain with us, Axios' Alex Fitzpatrick writes.

• There were about 66,100 living WWII vets nationwide as of 2024, according to U.S. Department of Veterans Affairs projections.

Cities nationwide and abroad are holding events to commemorate today's anniversary.

• Festivals, commemorations and honorary paratrooper drops will be taking place across Normandy, France — the site of the 1944 landings that kicked off the Allies' liberation of Western Europe.

Generative AI is evolving so fast that cybersecurity leaders are tossing out the playbooks they wrote just a year or two ago, Axios Future of Cybersecurity author Sam Sabin writes.

• Why it matters: Defending against AI-driven threats, including autonomous attacks, will require companies to make faster, riskier security bets than they've ever had to before.

Major AI model makers have unveiled several new findings and security frameworks that underscore just how quickly state-of-the-art AI is advancing.

• Researchers recently found that one of Anthropic's new models, Claude 4 Opus, has the ability to scheme, deceive and potentially blackmail humans when faced with a shutdown.
• Google DeepMind unveiled a new security framework for protecting models against indirect prompt injection — a threat in which a bad actor manipulates the instructions given to an LLM.

Case in point: A bad actor could trick an AI agent into handing over internal documents simply by embedding a hidden instruction in what looks like a normal email or calendar invite.

This memorable map shows how President Trump remade America's political divide, demographically and geographically, as reported by the N.Y. Times' Shane Goldmacher, June Kim and Christine Zhang:

• In the past three elections, Trump increased the Republican Party's share of the presidential vote in 46% of America's counties — 1,433 out of 3,143.
• Democrats grew their vote in each of the past three elections in only 57 counties — under 2%.

Why it matters: "The steady march to the right at the county level reveals not just the extent of the nation's transformation in the Trump era but also the degree to which the United States now resembles two countries charging in opposite directions," The Times reports.

• The Times podcast "The Daily" calls it a "1,400-County Crisis for Democrats."

🧮 By the numbers: "435 counties voted more Democratic in 2024 than did so in 2012, by an average improved margin of 8.8 percentage points," The Times found.

• "2,678 counties became more Republican, by an average of 13.3 percentage points. That's six times as many counties moving toward the G.O.P. than toward the Democratic Party — and by a substantially wider margin."

📈 Latino gains: "The biggest swing in the nation since 2012, moving 89 percentage points in Mr. Trump's favor, occurred in Starr County, which includes Rio Grande City and borders Mexico," the four-election analysis found. "It is also the nation's most predominantly Latino county, with a 96 percent Hispanic voting-age population."

• "Trump steadily improved his vote share over the three campaigns by more than 50 percentage points in seven heavily Hispanic counties in South Texas."

💡 Other findings:

• "Republicans are overwhelmingly making gains in working-class counties."
• "Democrats are improving almost exclusively in wealthier areas."
• "Republicans are running up the score in counties where fewer people have attended college."
• "Democrats are gaining ground in a small sliver of the best-educated enclaves."

🎓 Stunning stat: Only one of the 1,500 counties with the smallest proportion of college graduates (less educated counties) "voted steadily more Democratic over the last three elections. Republicans steadily grew their vote share in more than two-thirds of those less-educated counties."

• That one county was Barrow County, Ga. — in Atlanta's fast-growing exurbs.

Retailers are supercharging their store brands to boost sales and keep prices low in the face of rising tariff pressures, Axios' Kelly Tyko writes.

• Why it matters: The popularity of private-label products could soar as tariffs threaten to drive national brand prices higher.

Store brands aren't immune to tariffs, but large retailers have better leverage to negotiate terms with suppliers and reduce production costs.

• Retailers have been diversifying where their private brand products are manufactured and pushing for more American-made products.

Zoom in: A poster child for the private brand is discount grocer Aldi. Scott Patton, the chain's chief commercial officer, told Axios just 4% of its assortment "is impacted by tariffs."

• Walmart CEO Doug McMillon told Axios that the retailer has more "visibility and control over what happens" with store brands.
• Costco has been adding new products to its Kirkland Signature brand and seeing those sales outpace the company's overall numbers.
