Live from NPR News in Washington, I'm Rylan Barton. Department of Homeland Security Secretary Christine Nome says

federal agents in Minneapolis will be required to wear body cameras, effective immediately. The move

comes after federal agents shot and killed two people during President Trump's immigration crackdown

there. Bystander video has played an important role in documenting officers' actions. Trump says it was

Nome's decision. Well, it wasn't my decision. I would have, you know, I leave it to her. They generally

acquired its artificial intelligence company, XAI. As NPR's John Ruich reports, the idea is to take

AI into space. AI requires huge data centers, which require immense amounts of power and cooling. SpaceX

says in a statement, global electricity

demand for AI cannot be met with terrestrial solutions without imposing hardship on communities

and the environment. So SpaceX says space-based AI is the answer. Satellites harnessing

solar power, it says, will transform the ability to scale AI's computing power.

The tie-up also has a financial angle.

Reuters reported last week that SpaceX made $8 billion in profit last year on $15 to $16 billion in revenue.

XAI, meanwhile, reportedly burns through about a billion dollars a month.

It's also been the subject of controversy, with its Grock Chatbot accused of generating

non-consensual nude images, spreading conspiracy theories, and creating anti-Semitic content.
