WHCD Shooter Arrested

A gunman is in custody after storming the White House Correspondents’ Association dinner Saturday. President Donald Trump, whom the acting attorney general described as the likely target, is unharmed. See photos here.

The attack happened shortly after 8:30 pm ET, when police say a man armed with a shotgun, handgun, and multiple knives rushed past security at the Washington Hilton in downtown Washington, DC. Secret Service agents intercepted the gunman in the lobby while others escorted Trump out of the ballroom, and guests took cover. One Secret Service agent was shot in his bulletproof vest and later released from the hospital. See footage of the attack here.

The suspect is Cole Allen, a 31-year-old teacher from California who released a manifesto suggesting he sought to target administration officials. Trump says the dinner will be rescheduled within 30 days in remarks shortly after the attack (watch remarks).

 

Musk v. Altman

Elon Musk’s lawsuit against OpenAI, its CEO Sam Altman, and several others (including Microsoft) heads to court today with jury selection in Oakland, California. Opening arguments are expected tomorrow.

Musk cofounded OpenAI alongside Altman and several others in 2015 with a founding mission to develop artificial intelligence to benefit all humanity, unencumbered by corporate interests (see mission statement). Musk alleges he was misled when he donated tens of millions of dollars on the understanding it would remain a nonprofit; OpenAI transitioned to a public benefit corporation in October of last year. The trial—which centers on two claims, unjust enrichment and breach of charitable trust—comes in the lead-up to OpenAI’s potential public filing later this year. The company is targeting a $1T valuation. 

Musk seeks up to $134B to be returned to OpenAI's nonprofit arm, and wants OpenAI to be forced to return to nonprofit status. Among high-profile tech leaders who could testify are Musk, Altman, OpenAI cofounder Greg Brockman, and Microsoft CEO Satya Nadella.

Marathon Record Falls

The longstanding two-hour marathon milestone was broken in London over the weekend—not just by one competitor, but two. Kenyan Sabastian Sawe finished the race in 1:59:30, finishing 11 seconds ahead of Ethiopia’s Yomif Kejelcha (in what was the latter’s first official marathon). 

The sub-two-hour mark was unofficially broken in 2019 by Eliud Kipchoge, but had never been reached in a sanctioned race. Both Sawe and Kejelcha ran in a newly debuted Adidas shoe model weighing less than 100 grams (roughly equal to a deck of cards) and designed to return energy from sole compression with each step. The women’s winner, Ethiopia’s Tigst Assefa, also wore the shoes and finished in 2:15:41.  

The winning time is equivalent to running a mile in 4 minutes and 33 seconds, 26 times in a row. See how the development of energy return technology in shoes has pushed elite runners to previously unattainable speeds (w/video).
