President Donald Trump , talking to reporters Sunday at his Doonbeg golf resort in Ireland, brushed off the idea that AI development needs a brake. The U.S. is ahead of China, he said, and “whoever wins AI wins.” He allowed that “we can put guardrails,” but then offered none.

The warnings, Trump said, come from unnamed “negative forces” floating “things that won't happen.” Pressed later on whether he was minimizing the risk, he said, “I’m not downplaying,” and called AI “more good than bad, but by a lot.” That tracks for someone who loves posting AI-generated images of themselves and who claimed to have made “billions” for the country on AI-related stocks.

Timing matters here. The remarks landed a day after Anthropic CEO Dario Amodei published an essay urging labs and governments to slow capability gains, citing loss of control, cyberattacks and bioterrorism, and calling for third-party evaluators. Elon Musk and OpenAI’s Sam Altman publicly agreed.

As warnings rapidly mount over the pace and potential dangers, the top Republican and Democrat in the House agreed on Sunday that Congress should put guardrails in place, but would not commit to specific policies or a timeline for doing so. Speaker Mike Johnson, Republican of Louisiana, urged caution in an interview with NBC’s “Meet the Press,” saying that the House could not hastily pass regulations and that lawmakers needed to ensure American companies remain competitive with Chinese AI firms.

Xi Jinping visits the White House later this month, though the exact date and format haven’t been confirmed. Whether AI safety makes the agenda—or whether “whoever wins AI wins” is the entire American position going in—remains an open question.

A 40-year-old unvaccinated woman in Jefferson County, Pennsylvania, died of complications associated with measles. If confirmed, it’s the third measles-associated death in the state this year—and the first announced anywhere in the U.S. in 2026.

The other two Pennsylvania deaths were infants in Lancaster County. The state has now reported 676 cases across 37 counties and 124 hospitalizations. Fewer than 1% of confirmed cases were fully vaccinated—the single cleanest argument for the shot you'll read this week. Nationally, the CDC counts more than 3,000 cases, the worst resurgence since 1991. The agency still lists no 2026 measles deaths, and Health and Human Services Secretary Robert F. Kennedy Jr. has publicly disputed Pennsylvania's count. CDC Director Erica Schwartz said the agency wasn’t notified of this death and that Pennsylvania hasn't requested an Epi-Aid deployment.

Keep in mind, the case hasn’t been lab-confirmed, and the state health department hasn’t added the death to its official outbreak tally, saying it’s reviewing. But this doesn’t look great.

Alexander Zverev beat Ben Shelton 6-3, 7-6 (2), 5-7, 6-2 in Sunday’s U.S. Open final, banking $5.5 million and a second major in a single calendar year. Not bad for a guy who spent most of his career as the best player without a slam.

The French Open came first, and the pair makes Zverev the fourth man in the open era—after Jimmy Connors, Guillermo Vilas and Jannik Sinner—to win his first two majors in one season, the BBC reported. Injuries to Sinner and Carlos Alcaraz cleared the road. Shelton, 23, playing his first major final, came up short of becoming the first American man to win a slam since Andy Roddick in 2003, NBC News notes.

The complication doesn’t go away with the trophy: Zverev has denied abuse allegations from two former girlfriends, according to The Guardian. Shelton, meanwhile, has time. Sinner and Alcaraz will be back.
