A federal judge ruled Saturday that Kari Lake unlawfully led the US Agency for Global Media (USAGM) for several months last year and voided mass layoffs and other actions taken during that period to dismantle the agency. The US Agency for Global Media (USAGM) is an independent federal agency that oversees the Voice of America (VOA), the US’s largest and oldest international broadcaster, and provides grants to Radio Free Asia, Radio Free Europe and other news agencies. The Trump administration moved to defund the agency in early 2025 and appointed Lake to oversee the agency, but did not receive Senate confirmation for her role. Despite efforts to defund the agency, Congress appropriated half a billion dollars more than Lake requested in funding for the agency in 2026. In her role, Lake cut contracts and over 1,000 staff positions at the agency when she was appointed to the role on 31 July before she relinquished the position on 19 November. “Only the Appointments Clause or the Vacancies Act’s exclusive structure may authorize service as a principal officer, and Lake satisfies the requirements of neither the statute nor the Constitution,” US district court judge Royce C Lamberth wrote in the ruling. Lamberth leaned on the ruling by the third circuit court of appeals that ruled the appointment of Alina Habba, Donald Trump’s former personal lawyer, to lead the US attorney’s office in New Jersey was invalid. “Adopting Lake’s position would require the Court to find that the President can fill a first assistantship at any time during a vacancy in a Senate-confirmed office and then … elevate the first assistant to serve as the acting officer,” Lamberth said in the ruling. Lake said in a statement on social media: “We will appeal this outrageous ruling from an activist DC District Court Judge.” Lake also reposted a claim that the judge slept through arguments in the trial, responding “not surprised. Morbid obesity can cause massive issues with blood sugar.” Lamberth was app...

Key Points Nvidia still produces the best picks and shovels for the AI market. Its stock looks cheap relative to its growth potential. 10 stocks we like better than Nvidia › Nvidia (NASDAQ: NVDA), the world's largest producer of discrete GPUs, is the top artificial intelligence (AI) stock for many investors. Most of the world's top AI companies use its chips to train their AI algorithms, and it locks in those clients with its proprietary services. Nvidia's stock has already soared nearly 22,000% over the past decade -- lifting its market cap to $4.3 trillion and making it the world's most valuable company. However, the smart money will likely keep flowing into Nvidia's stock in March as the AI market continues expanding. Will AI create the world's first trillionaire? Our team just released a report on the one little-known company, called an "Indispensable Monopoly" providing the critical technology Nvidia and Intel both need. Continue » Why is Nvidia still a great growth stock? Nvidia once generated most of its revenue from selling gaming GPUs for PCs, but the lion's share now comes from its data center GPUs. Unlike CPUs, which are optimized for sequential tasks, GPUs are designed to process parallel tasks. That makes them better-suited for processing complex machine learning and AI tasks than stand-alone CPUs. Nvidia established a first-mover advantage in this market, and it maintained that lead with its Turing (2019), Ampere (2020), Hopper (2022), and Blackwell (2024) chip architectures. It plans to launch its next chip architecture, Rubin, in the second half of this year. It controls more than 90% of the discrete GPU market, while AMD (NASDAQ: AMD) holds a single-digit share. Nvidia's proprietary programming platform, CUDA (Compute Unified Device Architecture), enables developers to easily create AI applications optimized for its chips. The stickiness of that ecosystem, which includes other prisoner-taking services, reinforces its market dominance. Nvidia directl...

Netflix (NFLX 0.10%) let go of its Warner Bros. Discovery (WBD 0.21%) buyout attempt this week, and there was much rejoicing. The company isn't giving up on buyout ideas as a whole, though. A small part of the $2.8 billion breakup fee is already going into a much smaller deal. In news that sounds like a mad lib, Netflix just acquired an artificial intelligence company founded by the featured construction worker from Good Will Hunting. The company is called InterPositive, named after an old-school film preparation technique. Ben Affleck started it in 2022, and nobody really knew it existed until Thursday. So, what does the company do? InterPositive builds artificial intelligence (AI) tools for filmmakers. Its tools can fix lighting mistakes, fill in missing shots, replace backgrounds, and so forth. The focus is on adding AI smarts to the technical grunt work of production, not generating fake actors or writing scripts. Affleck and his team train their models on a closed soundstage using footage they control, which is a very different approach from scraping the entire internet and hoping for the best. Directors can also upload their own dailies to customize the InterPositive tool for a specific project. It's less "AI makes your movie" and more "AI handles the stuff you'd rather not spend three hours fixing in post-production." Why is Ben Affleck a part of this project? Affleck has been publicly interested in AI for a while, but more in a "this could help indie filmmakers" approach than a "robots will replace us all" way. From a conference presentation in 2024: "What AI is going to do is going to disintermediate the more laborious, less creative and more costly aspects of filmmaking that will allow costs to be brought down, that will lower the barrier to entry, that will allow more voices to be heard, that will make it easier for the people who want to make Good Will Huntings to go out and make it." You know, like the digital video editing tools that launched millions ...
