Below is our list of top advisors who provide advice and counsel concerning foreign investment and national security in the U.S. and abroad. Rankings are based on myriad criteria including experience, reputation, clients served, first-person interviews, references, reader recommendations, articles published, and — most importantly — one-to-one interactions with Foreign Investment Watch’s Editorial team.

This is an Editorial feature and is not paid. Please remember Foreign Investment Watch does not provide legal guidance or advice, and you should conduct your own due diligence when considering engaging outside counsel.

 

The Top Advisors 2026

Grigore Alexandru, Mubadala

One of a handful of inside counsel included in our “Top Advisors” list, Greg is a former Deputy Director at the Office of Foreign Investment Review at the DoD. An expert on the CFIUS national security review process — as well as FOCI, ITAR, EAR, and other regulations — Greg worked at Sidley until moving to Abu Dhabi to join Mubadala, the sovereign wealth fund of the United Arab Emirates. A long-time advisor to Foreign Investment Watch and repeat member of this list, Greg has contributed some of our most widely read articles, including an explanation of the CFIUS co-lead role, an overview of a unclassified CFIUS procedures document, and — most recently — insights on the hidden deal risks regarding reputational exposure across jurisdictions.

Nadia Asancheyev, DLA Piper

While relatively new to DLA Piper, Nadia is certainly not new to the CFIUS community. An expert on all things related to the Committee, Nadia also provides counsel and guidance regarding the DoJ’s Bulk Data Security Program. And she should know: She most recently served in the National Security Division of the DoJ, and served in the Foreign Investment Review Section as a regulator for both CFIUS and Team Telecom. At the National Security Division’s Office of Law & Policy, Nadia represented the DoJ at the National Security Council, and previously was the first Executive Director of the Georgetown Center on National Security and the Law. She can be reached at [email protected]

Keith Ausbrook, Guidepost Solutions

Keith is senior managing director at Guidepost, where he leads a national security practice engaged in CFIUS monitorships and advisory work. Previously, Keith had served as the Executive Secretary of the Homeland Security Council at the White House. He served as the special counsel to a House Committee investigating preparation for and response to Hurricane Katrina; was chief oversight counsel for the House Judiciary Committee following the September 11 attacks; and was the top lawyer on the House Government Reform and Oversight Committee that oversaw (among other matters) the theft of classified information by former National Security Advisor Sandy Berger. He is an expert on CFIUS mitigation, and provided a prescient guest column for us back in 2020 on common mitigation measures. Keith can be reached at [email protected].

Laura Black, White & Case

A 15-year veteran of the U.S. Treasury Department and four-time member of this list, Laura Black served as the first Director of Policy and International Relations of CFIUS. In addition to being the “chief drafter” of the regulations implementing FIRRMA, Laura played a leading role in the development of several global investment regimes, and spearheaded the Treasury Department’s engagement with dozens of foreign governments. She explained that foreign engagement strategy to our readers with great precision, and has provided ongoing insights on myriad topics, like the emergence of state-wide legislative proposals that may conflict with CFIUS’s mandate. Laura was also actively involved in the development of proposals for outbound foreign-investment reviews, and regularly provides valuable insights to the Foreign Investment Watch Editorial team. Not surprisingly, she’s also the go-to person for industry, and was recruited to interview new CFIUS head Chris Pilkerton at an industry event. She can be reached at [email protected].

Scott Boylan, StoneTurn

It’s rare that we find experts who’ve sat on literally every side of the CFIUS table. But that’s Scott Boylan. Formerly the CFIUS and Team Telecom representative at the Department of Homeland Security, Scott has also served at Treasury and Justice. But he’s also served as Chief Legal Officer for large CFIUS-mitigated companies, which means he’s participated in the negotiation of mitigation agreements from both sides. On top of that, he now regularly conducts CFIUS audits as an independent third-party. So, he’s structured CFIUS strategy, negotiated transactions before CFIUS, overseen compliance with CFIUS and FOCI mitigation agreements, and audited them from the outside. Scott has always carved out time to answer questions from Foreign Investment Watch editors, and has offered practical guidance for readers. He can be reached at [email protected].

Caroline Brown, Crowell & Moring

Since the moment we reported that Caroline Brown was leaving the Treasury Department’s Financial Crimes Enforcement Network to join Crowell & Moring, she has been a critical resource to the Foreign Investment Watch Editorial team. From commenting on Executive Orders to providing observations from CFIUS events, Brown is seemingly always available, always online, and always insightful. In addition to FinCEN, Caroline also served in the DoJ’s National Security Division, and at Treasury’s Office of General Counsel, Enforcement and Intelligence. A member of Crowell’s National Security Practice steering committee, she can be reached at [email protected].

John Carlin, Paul Weiss

Chair of Paul Weiss’s National Security & CFIUS group, John Carlin previously served as Acting Deputy Attorney General and then Principal Associate Deputy Attorney General of the United States, as well as Assistant Attorney General for the DoJ’s National Security Division. He’s been involved in a number of recent high-profile cases, including one we covered involving the acquisition of iRobot by its Chinese contract manufacturer, Picea. Those who nominated John cited his experiences with “high stakes” transactions involving AI, quantum and other critical and emerging technologies. He can be reached at [email protected]

Charles Capito, Morrison Foerster

Charles makes our Top Advisors list for the third year in a row. A seasoned national security expert with deep CFIUS experience, Charles has been involved in securing clearances for some of the largest and most sensitive cases reviewed by CFIUS, and has been involved in all steps of the CFIUS process, from assessing risk and presenting cases before the Committee, to negotiating mitigation measures and implementing agreements. He has been a critical resource to the Foreign Investment Watch Editorial team for several years, providing perspective, context and insights both on-background and on-the-record, on topics ranging from legislative proposals to CFIUS deliberations.

She also regularly handles multi-jurisdictional transactions that require an assessment under the FDI regimes of non-U.S. countries, and provides ongoing CFIUS counsel to the venture capital arms of several major conglomerates, including those of Toyota, Samsung, LG and others. Christine has also taken on a leadership role in the sector, hosting the first of two “Women in CFIUS” lunch events in D.C., and moderating discussions with CFIUS officials.

Thomas Feddo, The Rubicon Advisors

For the fifth year in a row, Thomas Feddo makes our Top Advisors list. The founder of The Rubicon Advisors, Tom is perhaps best known as “the OG” Assistant Secretary for Investment Security at the U.S. Treasury Department, a presidentially-appointed, Senate-confirmed position responsible for overseeing all operations and activities of CFIUS. Since his departure from Treasury, he’s hosted a regular video series with Foreign Investment Watch called “Ten with Tom,” has testified several times before Congressional committees on outbound screening, and has been an invaluable resource to our Editorial team for insights that only a few people on the planet can provide. The Foreign Investment Watch team has Tom on speed dial, and he’s always quick to respond with insights and intel. He can be reached at [email protected].

He can be reached at [email protected].

Megan Gordon, Clifford Chance

Not many advisors can say they have extensive experience with the Outbound Investment Security Program, especially since it’s not even two years old, but Megan Gordon is one of them. The co-head of Clifford Chance’s U.S. Data Privacy and Cybersecurity Group, Megan has been deeply engaged with the outbound regime, helping companies manage risk exposure and designing compliance programs. Much of her practice these days involves complex cross-border and domestic issues arising from the OISP, and she’s spent time with the Foreign Investment Watch team describing some of the intricacies and unexpected consequences facing market participants. She can be reached at [email protected].

Josh Gruenspecht, Wilson Sonsini

A partner in the Washington, D.C., office of Wilson Sonsini, Josh has been involved in some of the most high profile cases before CFIUS, including transactions involving Broadcom, Sprint, and the Nokia-Alcatel-Lucent deal. Described by more than one person at “the most detail-oriented national security lawyer practicing today,” Josh has negotiated security agreements, information sharing agreements, and network and physical security plans and policies with CFIUS, DCSA, the FCC, and others. He also serves as CFIUS counsel to the National Venture Capital Association, and authored the model CFIUS language for risk allocation in venture capital investing. The rare lawyer with a hardcore engineering background — earlier in his career, he worked on network security R&D focused on device and network exploitation — Gruenspecht previously served as a Cybersecurity Fellow with the Center for Democracy and Technology.

Stephenie has been an invaluable advisor to the Foreign Investment Watch team, seemingly available 24×7, and her insights and webcasts on topics ranging from CFIUS trends to the pending outbound review have been timely and insightful, as have her cybersecurity and data privacy “review and outlooks.” She can be reached at [email protected].

Stephen Heifetz, Wilson Sonsini Goodrich & Rosati

No one has made CFIUS-watching more fun and entertaining than Stephen Heifetz. A partner in the National Security practice of Wilson Sonsini, Stephen previously served in the U.S. government as a CFIUS official, and in other national security positions at the CIA, Department of Homeland Security, and Department of Justice. He has been involved in more than 1,000 CFIUS matters, and serves as CFIUS counsel for the National Venture Capital Association. His contribution to our “Startup’s Guide to CFIUS” was the most widely read column in that special section, and he’s been an ongoing resource to the editors of Foreign Investment Watch for insights — and humor; perhaps a remnant from his days as an adjunct professor at Georgetown University Law Center. He’s been quite outspoken on deficiencies at CFIUS, and isn’t afraid to speak his mind; when Foreign Investment Watch wants a brilliant, insightful, contrarious view, it’s usually Stephen who can offer it up. He can be reached at [email protected].

Eric Johnson, Proskauer

Not many regulators go out of their way to engage with the media and transaction parties, but Eric was one of them. Most recently Principal Deputy Chief for the Foreign Investment Review Section at the DoJ’s National Security Division, Eric basically supervised the DOJ’s work involving CFIUS and Team Telecom, and was deeply involved in the Data Security Program. While at the DoJ, Eric spent time with Foreign Investment Watch readers explaining the proposal, and then unpacking the Protecting Americans from Foreign Adversary Controlled Applications Act (we credit him for cracking the acronym’s pronunciation).

The combination has given Ben hands‑on experience with nearly every facet of the CFIUS process, from reviewing transactions to negotiating mitigation agreements.

John can be reached at [email protected]

Nicole Kar, Paul Weiss

A partner and global co-chair of the Antitrust Practice at Paul Weiss in London, Nicole Kar has been our go-to expert on the UK’s National Security and Investment Act. Quoted by Foreign Investment Watch more times than we care to count, Nicole’s extraordinary understanding of the complex and constantly-changing European and UK foreign-investment review regimes has made her our resident expert on the NSIA; we’re apparently in good company, as Nicole advised the UK Parliament’s Foreign Affairs Committee on the passage of the bill. She provided a primer for our readers back in April 2022, and few months later broke down the first UK report on their new regime. Nicole can be reached at [email protected]

He later shared his insights with our readers during a “Ten Minutes On” video session, and has provided regular insights and behind-the-scenes tips to the Foreign Investment Watch Editorial team.

We’ve said it many times before: H.K. Park should be on our payroll.

A former Assistant to the Secretary of Defense on homeland security matters, H.K. spent nearly two decades at the advisory firm launched by former Secretary of Defense and Member of Congress William S. Cohen, where he led the firm’s Korea and Southeast Asia practices. An expert on helping companies think about expansion into foreign markets, particularly Asia, H.K. is one of the few experts on outbound foreign-investment regimes, and was the first to explain to our readers how national security audits could be a direct result of any outbound legislation or Executive Order.

An expert with an extraordinarily deep understanding of complex compliance and enforcement matters arising from CFIUS and Team Telecom cases, his “ten minutes on” session with Foreign Investment Watch was one of our most widely-viewed videos; his Q&A with us on lessons for dealing with CFIUS was considered “priceless” by readers. David has provided constant guidance and insight to the editors of Foreign Investment Watch on topics related to global trade, information communications technology, critical and emerging technology, and more. Now a partner at Morgan Lewis, David can be reached at [email protected].

Mark Plotkin, Covington

Few firms do as much CFIUS work as Covington, and Mark Plotkin is the reason why. While maintaining an under-the-radar profile, Mark has a well-known reputation as one of the preeminent CFIUS experts. Sometimes known as the “dean of the CFIUS bar,” Mark and his team have been involved in some of the most high-profile transactions involving Chinese parties, from China National Offshore Oil Corporation’s $1.5 billion acquisition of Nexen, to the sale of CIT Group to China’s Avolon Holdings. And he’s been doing it longer than most: He helped secure CFIUS clearance for GlobalFoundries’ acquisition of IBM’s semiconductor business more than a decade ago. Mark can be reached at [email protected]

Bridget Reineking, Cooley

Previously senior counsel and co-lead CFIUS counsel at the Office of the General Counsel at Treasury, Bridget Reineking has deep experience with the Committee, having supervised the legal analyses and resolution of more than 600 transactions reviewed by CFIUS.
