Former DOJ employees make up both its in-house team and members of outside counsel firms it employs. The company has hired three former DOJ officials into regulatory roles since May 2022, and one before that in 2021, according to public information including social media profiles. Google also uses four different outside counsel firms loaded with nearly 20 former DOJ officials, many of whom worked in the Antitrust Division at various times.
Such hiring to its internal regulatory team is a reflection of the intense scrutiny Google is facing from governments around the world. It can be a signal that a company anticipates dealing with regulatory challenges in years to come, even if it doesn’t know exactly what form it’ll take yet, according to two former government officials.
“When companies find themselves under intense scrutiny from regulatory authorities, antitrust law or otherwise, they make moves like this,” said Bill Kovacic, a former Federal Trade Commission chair who now teaches antitrust law at George Washington University.
Google now faces two antitrust challenges from the DOJ, both to its search and ad tech businesses, and additional challenges from a slew of state attorneys general. Regulators around the world, including in Europe and Australia, have also presented policy and enforcement hurdles.
Google’s hiring is not surprising for a company under such a microscope, according to Doug Melamed, a former acting assistant attorney general at the DOJ Antitrust Division who’s now a scholar-in-residence at Stanford Law School.
The company had already been fighting one complex antitrust case that would likely require a team of 10 to 15 lawyers alone, according to Melamed, when the Department brought its second antitrust challenge against the company earlier this year.
“They don’t have the capacity to handle a case like that just sitting idle,” Melamed said. “They’ve got to now think about well, what outside lawyers are available that have to have the time and expertise to handle this case? And then, do I have the in-house capability to support it and supervise it?”
The added threat of new legislation targeting Google’s business, and that of other tech firms, looms. In the near term, it appears that a massive lobbying campaign by the industry has successfully delayed the most disruptive reforms. But the possibility of renewed energy around that legislation still hangs over the industry, and a company like Google “can take nothing for granted now,” Kovacic said, adding that’s likely a reason for the company to build out its regulatory forces.
“New entrants and new innovations are driving competition and delivering value for America’s consumers, publishers, and merchants,” a Google spokesperson said in a statement for this story. “We’re proud of our services and we look forward to making our case in court.”
Revolving door hiring
Alphabet now has at least five former DOJ staffers on its legal team, including Google’s director of competition Kevin Yingling, who’s been with the company for more than a decade and worked as a trial attorney at the Department of Justice from 2000 to 2005, according to his LinkedIn.
The company hired Kate Smith as counsel for Alphabet’s regulatory response, investigations and strategy unit in February 2021, according to LinkedIn. Smith was a trial attorney in the DOJ’s Civil Frauds division from September 2015 until January 2021.
In May 2022, according to LinkedIn, Alphabet hired Mike Kass, a former trial attorney in the DOJ’s Civil Fraud section, as its regulatory and litigation counsel for products.
A month later, the company hired Seema Mittal Roper as counsel on its regulatory response team. Mittal Roper worked as an assistant U.S. attorney for the DOJ in Maryland from 2013 to 2018, according to LinkedIn.
Most recently, the company hired Jack Mellyn as strategy counsel on its regulatory team. Mellyn was previously an attorney advisor and then acting assistant chief in the DOJ’s competition policy and advocacy section, according to a previously available social media profile.
It’s not clear which employees are working on the specific matters before the DOJ and Kass’ role appears focused outside of antitrust. It’s likely these employees never worked on Google-related matters they’re dealing with now during their time in government, given their dates and areas of previous employment, as well as federal ethics rules that bar certain conflicts.
But experts say this kind of hiring, which is common among businesses faced with regulatory scrutiny, can still be beneficial to a company because of the unique insight, touch or credibility that an ex-government attorney might hold when it comes to their former colleagues.
“There are lots of lawyers out there. But only alumni of an office really understand how that office works,” said Jeff Hauser, executive director of the Revolving Door Project, which tracks the business ties of executive branch officials. “That means its strengths and weaknesses, that means the tendencies of people in that office. And they can therefore give much more concrete intelligence and better-informed advice to their client.”
Hauser said this may mean the lawyers could advise a client or employer to flood the agency with information rather than comply with a certain document request, knowing that the enforcers don’t have the capacity to deal with it. Or, they might suggest strategies to approach a deposition, knowing the government staffer conducting it.
“A lawyer who’s had experience in the government doesn’t bring information about the specific matters of the companies involved, but rather brings a general perspective about how the agency is approaching these kinds of problems,” Melamed said.
Enforcement agencies also often have to trust whether they believe the target of an investigation has complied with its requests. Hauser said the agencies may be more inclined to take the word of their former colleagues, compared to a more removed attorney.
A recent event shows what can happen when that trust is broken. The DOJ last month accused Google of destroying chat messages it should have kept under a litigation hold related to the investigation. The DOJ made the accusation in a legal filing after Epic Games raised the concern in its own antitrust litigation against Google.
A Google spokesperson said in a statement at the time of the DOJ’s filing that they “strongly refute the DOJ’s claims.”
Google also works with outside counsel firms on its antitrust cases, including Axinn, Freshfields, Ropes & Gray and Wilson Sonsini, based on reports, statements and legal filings. Those firms collectively have around 20 former DOJ employees on their staff, many of them working in antitrust. Though these attorneys may not all work on Google matters, the firms themselves often tout the benefit of former government officials in bringing a helpful perspective to clients.
For example, Freshfields says on its website that its “deep bench of former DOJ and FTC trial attorneys gives us unique insight into how the enforcement agencies approach enforcement in general and litigation in particular.”
Kovacic said agency experience is something companies look for in hiring outside firms.
“In deciding who to retain, what law firm to retain or what economic consultancy to retain, they would place a lot of weight on how many former government officials are in those firms,” Kovacic said.
Freshfields attorneys Julie Elmer and Eric Mahr have led Google’s defense against an advertising technology monopolization case brought by a group of states led by Texas, The New York Times reported in 2021. And Bloomberg Law reported this year that Mahr will also lead its defense in the ad tech case brought by the DOJ.
Mahr was director of litigation for the DOJ Antitrust Division from 2015 to 2017, according to the Freshfields site, and Elmer worked as a trial attorney in the Antitrust Division from 2015 to 2020, according to her LinkedIn profile.
Revolving door hiring goes both ways between the public and private sectors, with government officials often working for previous employers or clients who become relevant in their work. For example, DOJ antitrust chief Jonathan Kanter previously worked for clients including Microsoft and Yelp which have complained of Google’s allegedly anticompetitive behavior.
Ultimately, however, Kanter was cleared to work on cases and investigations involving Google, despite the company’s suggestion that his past work should cast doubt on his ability to be fair in such matters.
The DOJ and Wilson Sonsini declined to comment. The three other firms mentioned did not immediately provide a comment for this story.
Limits for former government employees
There are limits on what former government officials can work on under federal ethics and Bar rules.
For example, the DOJ’s website says that former employees can’t represent someone before the government on an issue involving parties they “personally and substantially” worked on during their time in government. For two years after leaving the Department, a former employee also cannot represent anyone before the government in a matter involving parties they know “was pending under his official responsibility for the last year of government service and in which the U.S. is a party or has a substantial interest.”
And for one year after leaving the agency, former senior employees cannot represent someone before the agency “with the intent to influence” the DOJ on a pending matter or one in which it has an interest.
Personal and substantial work on a matter within government doesn’t depend on the length of time devoted to it, but the role a person played in potentially influencing the outcome or direction, according to Virginia Canter, the chief ethics counsel at Citizens for Responsibility and Ethics in Washington (CREW) who previously advised government officials on ethics at agencies including the Securities and Exchange Commission and the Treasury Department.
But even if a former government official can’t work on a specific matter they were privy to during their earlier employment, their insight might still be useful to a company.
“You can read about it, but when you’re actually part of dealing with these cases, you know that there are certain factors that are going to either act as mitigating or … that are going to more favorably incline you to bring a case,” Canter said. “It’s just your general knowledge and experience.”
When companies hire former government officials, they may also have the idea that those employees will be viewed more favorably by the current regime.
“Maybe there’s just this general impression that they’re trying to surround themselves with what will be perceived by their former colleagues as the good guys,” Canter hypothesized.
Some might argue that experience could be beneficial to the government in some cases, Canter noted. A former government employee might have a deeper understanding of the importance of compliance or providing certain information to officials, for example, having seen up close what could be at stake if they don’t.
Hauser said it’s unlikely DOJ leadership, especially Kanter, who has made a point to bring more aggressive cases in the tech space and overall, would be overly swayed to view things Google’s way in ongoing matters. But, he said, the impact of former DOJ staff employed by Google could be more influential in an emerging issue, where there’s an opportunity to leave a first impression on senior leadership about it.
The degree of this kind of influence may be relatively small on the level of an individual case, Hauser said, but for a company under such a high degree of regulatory scrutiny, it could add up.
“You’re talking about billions and billions of dollars of potential implications for Google’s net worth,” Hauser said. “Relatively small changes in the scope of the investigation, the timeframe of the investigation, can be very big, even if they don’t go to the overall question of will there be any lawsuits by the Justice Department against Google.”

Singapore-based software firm Horizon Quantum on Wednesday said it has become the first private company to run a quantum computer for commercial use in the city-state, marking a milestone ahead of its plans to list in the U.S.
The start-up, founded in 2018 by quantum researcher Joe Fitzsimons, said the machine is now fully operational. It integrates components from quantum computing suppliers, including Maybell Quantum, Quantum Machines and Rigetti Computing.
According to Horizon Quantum, the new computer also makes it the first pure-play quantum software firm to own its own quantum computer — an integration it hopes will help advance the promising technology.
“Our focus is on helping developers to start harnessing quantum computers to do real-world work,” Fitzsimons, the CEO, told CNBC. “How do we take full advantage of these systems? How do we program them?”
Horizon Quantum builds the software tools and infrastructure needed to power applications for quantum computing systems.
“Although we’re very much focused on the software side, it’s really important to understand how the stack works down to the physical level … that’s the reason we have a test bed now,” Fitzsimons said.
Quantum race
Horizon Quantum hopes to use its new hardware to accelerate the development of real-world quantum applications across industries, from pharmaceuticals to finance.
Quantum systems aim to tackle problems too complex for traditional machines by leveraging principles of quantum mechanics.
For example, designing new drugs, which requires simulating molecular interactions, or running millions of scenarios to assess portfolio risk, can be slow and computationally costly for conventional machines. Quantum computing is expected to provide faster, more accurate models to tackle these problems.
A top executive at Google working on quantum computers told CNBC in March that he believes the technology is only five years away from running practical applications.
Still, today’s quantum systems remain in the nascent stages of development and pose many engineering and programming challenges.
Investment in the space has been rising, however, as major tech companies report technological breakthroughs. Alphabet, Microsoft, Amazon and IBM, along with the U.S. government, are already pouring millions into quantum computing.
Investor attention also received a bump in June after Nvidia chief executive Jensen Huang offered upbeat remarks, saying quantum computing is nearing an “inflection point” and that practical uses may arrive sooner than he had expected.
Nasdaq listing
Horizon Quantum’s announcement comes ahead of a merger with dMY Squared Technology Group Inc., a special purpose acquisition company. The deal, agreed upon in September, aims to take Horizon public on the Nasdaq under the ticker “HQ.”
The software firm said in September that the transaction valued the company at around $503 million and was expected to close in the first quarter of 2026.
The launch of its quantum computer also helps cement Singapore’s ambition to be a regional quantum computing hub. The city-state has invested heavily in the technology for years, setting up its first quantum research center in 2007.
Before Horizon Quantum’s system came online, Singapore reportedly had one quantum computer, used primarily for research purposes. Meanwhile, U.S.-based firm Quantinuum plans to deploy another commercial system in 2026.
Singapore’s National Quantum Strategy, unveiled in May 2024, committed 300 million Singapore dollars over five years to expand the sector, with a significant portion directed toward building local quantum computer processors.
In May 2024, the National Quantum Strategy (NQS), Singapore’s national quantum initiative, pledged around S$300 million over five years to strengthen development in the sector, with a significant portion directed toward building local quantum computer processors.
The moon vacuum, which was unveiled on Wednesday by Blue Origin at Amazon‘s re:Invent 2025 conference in Las Vegas, was built using critical technology from startup Istari Digital.
“So what it does is sucks up moon dust and it extracts the heat from it so it can be used as an energy source, like turning moon dust into a battery,” Istari CEO Will Roper told CNBC’s Morgan Brennan.
Spacecraft carrying out missions on the lunar surface are typically constrained by lunar night, the two-week period every 28 days during which the moon is cast in darkness and temperatures experience extreme drops, crippling hardware and rendering it useless unless a strong, long-lasting power source is present.
“Kind of like vacuuming at home, but creating your own electricity while you do it,” he added.
The battery was completely designed by AI, said Roper, who was assistant secretary of the Air Force under President Donald Trump‘s first term and is known for transforming the acquisition process at both the Air Force and, at the time, the newly created Space Force.

A major part of the breakthrough in Istari’s technology is the way in which it handles and limits AI hallucinations.
Roper said the platform takes all the requirements a part needs and creates guardrails or a “fence around the playground” that the AI can’t leave while coming up with designs.
“Within that playground, AI can generate to its heart’s content,” he said.
“In the case of Blue Origin’s moon battery, [it] doesn’t tell you the design was a good one, but it tells us that all of the requirements were met, the standards were met, things like that that you got to check before you go operational,” he added.
Istari is backed by former Google CEO Eric Schmidt and already works with the U.S. government, including as a prime contractor with Lockheed Martin on the experimental x-56A unmanned aircraft.

Nvidia CEO Jensen Huang said he met with President Donald Trump on Wednesday and that the two men discussed chip export restrictions, as lawmakers consider a proposal to limit exports of advanced artificial intelligence chips to nations like China.
“I’ve said it repeatedly that we support export controls, and that we should ensure that American companies have the best and the most and first,” Huang told reporters on Capitol Hill.
Lawmakers were considering including the Guaranteeing Access and Innovation for National Artificial Intelligence Act in a major defense package, known as the National Defense Authorization Act. The GAIN AI Act would require chipmakers like Nvidia and Advanced Micro Devices to give U.S. companies first pick on their AI chips before selling them in countries like China.
The proposal isn’t expected to be part of the NDAA, Bloomberg reported, citing a person familiar with the matter.
Huang said it was “wise” that the proposal is being left out of the annual defense policy bill.
“The GAIN AI Act is even more detrimental to the United States than the AI Diffusion Act,” Huang said.
Nvidia’s CEO also criticized the idea of establishing a patchwork of state laws regulating AI. The notion of state-by-state regulation has generated pushback from tech companies and spurred the creation of a super PAC called “Leading the Future,” which is backed by the AI industry.
“State-by-state AI regulation would drag this industry into a halt and it would create a national security concern, as we need to make sure that the United States advances AI technology as quickly as possible,” Huang said. “A federal AI regulation is the wisest.”
Trump last month urged legislators to include a provision in the NDAA that would preempt state AI laws in favor of “one federal standard.”
But House Majority Leader Steve Scalise (R-LA) told CNBC’s Emily Wilkins on Tuesday the provision won’t make it into the bill, citing a lack of sufficient support. He and other lawmakers will continue to look for ways to establish a national standard on AI, Scalise added.
