The battle between federal and state authority reached a flashpoint this week as courts, prosecutors, and former Fed chairs all weighed in on what critics are calling an unprecedented assault on institutional independence. Meanwhile, the tech sector grapples with AI's dual promise and peril, from record chip profits to deepfake lawsuits.
FEDERAL POWER UNDER SCRUTINY
A federal judge in Minneapolis issued a significant ruling preventing DHS agents from arresting peaceful protesters or using tear gas against demonstrators not obstructing immigration enforcement operations—a direct response to a violent incident during a January 14 enforcement action (Minneapolis Star Tribune). The ruling came as the Justice Department simultaneously launched a criminal investigation into Minnesota's Governor and Minneapolis's Mayor over their handling of federal operations.
The DOJ's expanding investigative reach drew sharp rebuke from an unusual coalition: former Federal Reserve chairs joined current chair Jerome Powell in denouncing a separate criminal investigation into Powell's tenure as a "politically motivated attack" on the central bank's independence (Wall Street Journal, Financial Times). The Trump administration, meanwhile, is deploying additional federal agents to Minnesota and has proposed capping credit card interest rates at 10%.
TECH'S TRILLION-DOLLAR TUG OF WAR
The AI infrastructure race is reshaping global supply chains at breakneck speed. SK Hynix and TSMC reported record profits driven by insatiable demand for AI chips, even as China drafts new purchase rules for Nvidia's H200 processors and Beijing orders firms to abandon U.S. and Israeli cybersecurity software (Reuters, Bloomberg). The U.S. responded with 25% tariffs on AI chip imports.
In a surprising twist, OpenAI secured a $10 billion computing deal with Cerebras—a direct competitor to its Microsoft partnership—while Elon Musk's lawsuit against OpenAI now seeks $134 billion in damages (TechCrunch). Musk's xAI faces its own legal troubles, with California's AG pursuing action over deepfakes and the EPA investigating illegal generator use at data centers.
Oracle shares plunged 13% on concerns about AI spending sustainability, while ClickHouse reached a $15 billion valuation and AI cloud startup Runpod hit $120 million in annual recurring revenue.
PLATFORM ACCOUNTABILITY COMES DUE
Google and Character.AI are moving to settle lawsuits connected to teen suicides involving their products, marking a significant shift in how tech companies approach liability for user harm (New York Times). X faces mounting criticism over its Grok AI generating nonconsensual sexual images, adding to the platform's regulatory headaches.
TikTok returned to U.S. app stores following a pause in its ban—and quietly launched an app called "PineDrama"—while Google drew backlash for removing cultural observances like Women's History Month from its calendar product. Sam Altman's influence on AI policy continues to grow through direct engagement with President Trump.
GLOBAL REALIGNMENTS
President Trump threatened tariff retaliation against any nation opposing U.S. control over Greenland, while announcing a new Gaza "Board of Peace" featuring Tony Blair and Marco Rubio (Associated Press). The administration is also escalating pressure on Venezuelan President Nicolás Maduro through oil tanker seizures and sanctions on his family.
Canada broke decisively with U.S. trade policy by slashing its 100% tariff on Chinese electric vehicles and signing a new trade agreement with Beijing covering canola and EVs (Globe and Mail, CBC). In Uganda, longtime leader Yoweri Museveni holds a commanding lead in ongoing elections.
