Dina Powell McCormick, who was a member of President Donald Trump’s first administration, has resigned from Meta’s board of directors.

Powell McCormick, who previously spent 16 years working at Goldman Sachs, notified Meta of her resignation on Friday, according to a filing with the SEC. The filing did not disclose why McCormick was stepping down from Meta’s board, but said her resignation was effective immediately.

Meta does not plan on replacing her board role, according to a person familiar with the matter who asked not to be named due to confidentiality. Powell McCormick is considering a potential strategic advisory role with Meta, but nothing has been decided, the person said.

Powell McCormick joined Meta’s board in April along with Stripe co-founder and CEO Patrick Collison. Meta CEO Mark Zuckerberg said in a statement at the time that the two executives “bring a lot of experience supporting businesses and entrepreneurs to our board.”

Powell McCormick served as a deputy national security advisor to President Trump during his first stint in office and was also an assistant secretary of state during President George W. Bush’s administration.

She is married to Sen. Dave McCormick, R-Pa, who took office in January.

Powell McCormick is the vice chair, president and head of global client services at BDT & MSD Partners, which formed in 2023 after the merchant bank BDT combined with Michael Dell’s investment firm MSD.

With her departure, Meta now has 14 board members, including UFC CEO Dana White, Broadcom CEO Hock Tan and former Enron executive John Arnold.

Elon Musk‘s 2018 CEO pay package from Tesla, worth some $56 billion when it vested, must be restored, the Delaware Supreme Court ruled Friday.

“We reverse the Court of Chancery’s rescission remedy and award $1 in nominal damages,” the judges wrote in their opinion.

In the decision, the Delaware Supreme Court judges said a lower court’s decision to cancel Musk’s 2018 pay plan was too extreme a remedy and that the lower court did not give Tesla a chance to say what a fair compensation ought to be.

The decision on the appeal in this case, known as Tornetta v. Musk, likely ends the yearslong fight over Musk’s record-setting compensation.

Musk’s net worth is currently estimated at around $679.4 billion, according to the Forbes Real Time Billionaires List.

Dorothy Lund, a professor at Columbia Law School, told CNBC that while the Friday opinion may restore the 2018 pay plan for Musk, it leaves the rest of the lower court’s decision unaddressed and intact.

“The court had previously decided that Musk was a controlling shareholder of Tesla and that the Tesla board and he arranged an unfair pay plan for him,” she said. “None of that was reversed in this decision.”

“We are proud to have participated in the historic verdict below, calling to account the Tesla board and its largest stockholder for their breaches of fiduciary duty,” lawyers representing plaintiff Richard J. Tornetta said in an e-mailed statement.

Tesla did not immediately respond to requests for comment.

The Delaware Supreme Court issued the order per curiam with no single judge taking credit for writing the opinion and no dissent noted.

Musk’s 2018 CEO pay package from Tesla, comprised of 12 milestone-based tranches of stock, was unprecedented at the time it was proposed. After it was granted, the pay plan made Musk the wealthiest individual in the world.

Tesla shareholder Tornetta sued Tesla, filing a derivative action in 2018, accusing Musk and the company’s board of a breach of their fiduciary duties.

Delaware’s business-specialized Court of Chancery decided in January 2024 that the pay plan was improperly granted and ordered it to be rescinded.

In her decision, Chancellor Kathaleen McCormick also found that Musk “controlled Tesla,” and that the process leading to the board’s approval of his 2018 pay plan was “deeply flawed.”

Among other things, she found the Tesla board did not disclose all the material information they should have to investors before asking them to vote on and approve the plan.

After the earlier Tornetta ruling, Musk moved Tesla’s site of incorporation out of Delaware, bashed McCormick by name in posts on his social network X, formerly Twitter, where he has tens of millions of followers, and called for other entrepreneurs to reincorporate outside of the state.

Tesla also attempted to “ratify” the 2018 CEO pay plan by holding a second vote with shareholders in 2024.

In November, Tesla shareholders voted to approve an even larger CEO compensation plan for Musk.

The 2025 pay plan consists of 12 tranches of shares to be granted to the CEO if Tesla hits certain milestones over the next decade and is worth about $1 trillion in total. The new plan could also increase Musk’s voting power over the company from around 13% today to around 25%.

Shareholders had also approved a plan to replace Musk’s 2018 CEO pay if the Tornetta decision was upheld on appeal. That plan is now nullified.

As CNBC previously reported, a law firm that currently represents Tesla in this appeal penned a bill to overhaul corporate law in Delaware earlier this year. The bill was passed by the Delaware legislature in March, and if it had applied retroactively, it could have affected the outcome of this case.

With the AI talent wars heating up between companies like OpenAI, Meta and Anthropic, one way Google has been competing is by aggressively rehiring former employees.

Some 20% of software engineers working on artificial intelligence that Google hired in 2025 were so-called boomerang employees, an increase from prior years, CNBC has learned. A Google spokesperson confirmed the statistic remains accurate as of December, and said the company saw a jump in the number of AI researchers coming from major competitors compared to 2024.

“We’re energized by our momentum, compute, and talent — engineers want to work here to keep building groundbreaking products,” the spokesperson said in a statement.

John Casey, Google’s head of compensation, recently told employees in a meeting about the rehiring. Casey said AI-focused software engineers are drawn to Google’s deep pockets and hefty computational infrastructure that’s needed to perform advanced AI work, according to audio reviewed by CNBC.

Google has a large pool of ex-employees to mine, particularly after its largest ever round of layoffs in early 2023, when parent company Alphabet cut 12,000 jobs, reducing headcount by 6%. That followed a market downturn driven by soaring inflation and rising interest rates. Google has since continued with rolling layoffs and buyouts.

Across the industry, employee boomerangs are up, according to data published earlier this year by ADP Research, with the sector it classifies as information showing the starkest numbers.

Google has been racing to catch up in generative AI after a slow start that followed OpenAI’s release of ChatGPT in late 2022. After fumbling a number of product rollouts, the company has bounced back this year, thanks to hefty investments in AI infrastructure and the success of its Gemini app. Google announced its latest model, Gemini 3, last month.

Alphabet’s stock price is up more than 60% this year, outperforming all of its megacap peers.

As a historical hotbed of engineering and innovation, Google has long been a place where competitors have turned to try and poach talent. That’s still the case.

Earlier this year, Microsoft hired around two dozen employees from Google’s DeepMind AI research lab, CNBC reported in July. OpenAI, meanwhile, has opened its wallets wide, along with Meta. OpenAI CEO Sam Altman told employees in June that Meta had been offering $100 million signing bonuses, and that he was aggressively trying to retain staffers.

Late last year, Google brought back a major figure in AI: Noam Shazeer.

Shazeer and Daniel De Freitas left Google in 2021 to start AI platform Character.AI, reportedly departing after Google rebuffed their attempts to try and get the company to push its internal chatbot forward.

Along with other members of the Character.AI research team, Shazeer and De Freitas rejoined DeepMind in August 2024 under a licensing deal for the startup’s technology.

Over the last year, Google has taken more risks, shipping products more quickly, even if they aren’t viewed as completely ready. Google has also made a companywide effort to remove bureaucracy, enacting widespread employee buyouts and eliminating more than one-third of its managers overseeing small teams, CNBC reported in August.

Google co-founder Sergey Brin, who came out of retirement in 2023, has at times personally reached out to prospective candidates to recruit them, according to people familiar with the matter who asked not to be named because they weren’t authorized to speak to the media. Meta CEO Mark Zuckerberg has also reportedly reached out to researchers on behalf of his company.
