47 Matches Against International Databases
Forty-seven companies that members of Congress actively trade match records in international sanctions, watchlist, and regulatory databases. The figure comes from a CapitolExposed cross-reference of every company in our congressional trading database against the OpenSanctions global dataset, which covers sanctions lists from the United States, European Union, United Nations, China, Iran, and dozens of other jurisdictions.
The matches range from counter-sanctions, where adversarial governments have sanctioned American companies in retaliation for U.S. foreign policy, to regulatory flags, where international financial authorities have placed restrictions on trading in certain securities, to one company that appears on the actual U.S. Treasury Department's Office of Foreign Assets Control (OFAC) Specially Designated Nationals list.
Members of Congress trade these companies routinely. Nothing in the STOCK Act requires them to check whether a company they are buying or selling carries international sanctions designations. Nothing in congressional ethics rules flags trades in watchlisted companies. The system operates as though this information does not exist.
Defense Contractors: Sanctioned by the Countries They Build Weapons Against
Lockheed Martin, the largest defense contractor in the world and one of the most heavily traded stocks among members of Congress, matches records on both China's sanctions list (cn_sanctions) and Iran's sanctions list (ir_sanctions). The match confidence ranges from 77% to 100% depending on the dataset.
The reason is straightforward. China sanctioned Lockheed Martin for selling weapons to Taiwan. Iran sanctioned the company for its role in supplying military equipment used in the broader Middle East theater. From Beijing's and Tehran's perspectives, Lockheed Martin is a direct instrument of American military policy in their respective regions.
Members of Congress who sit on the Armed Services Committee, the Foreign Affairs Committee, and the Defense Appropriations subcommittee vote on the very weapons sales that triggered those sanctions. They authorize the foreign military financing that pays for Lockheed Martin's products. They approve the defense budgets that determine the company's revenue. And they trade its stock.
General Dynamics tells the same story. Matched on Iran's sanctions list at 98% confidence, General Dynamics builds submarines, armored vehicles, and weapons systems that the Iranian government considers direct threats to its national security. Congressional committee members who shape U.S. defense posture toward Iran simultaneously hold positions in a company that Iran has formally designated as a sanctions target.
The question these matches raise is not whether Congress is breaking any law. Members are not subject to Chinese or Iranian sanctions. The question is whether trading in companies that sit at the center of international military conflicts creates a financial incentive, however subtle, that compounds the existing conflicts of interest that the STOCK Act was supposed to address.
Energy and the Iran Sanctions Axis
Chevron, one of the largest oil companies in the world, matches Iran's sanctions list at 98% confidence. Iran has sanctioned several major Western energy companies for operating in sectors that compete with or undermine Iran's oil exports. Chevron's presence on that list reflects the geopolitics of global energy markets, where American companies and Iranian state interests are in direct competition.
Congressional trading in Chevron is widespread. The stock appears in portfolios across both chambers and both parties. Members who vote on Iran sanctions policy, oil export authorizations, and energy regulation trade a company that Iran considers hostile to its economic interests. The circularity is striking: Congress imposes sanctions on Iran, Iran retaliates by sanctioning American energy companies, and members of Congress trade those same companies while voting on the next round of sanctions.
Biotech and Technology: The China Factor
Illumina, the genomics and biotechnology company, matches China's sanctions list at 100% confidence. China has targeted several American biotech and technology firms as part of its broader response to U.S. export controls and technology restrictions. Illumina's inclusion reflects China's concern about American dominance in critical biotechnology sectors.
Members of Congress who serve on the Commerce and Science committees, which oversee biotechnology regulation and export controls, trade Illumina. They vote on the export restrictions that triggered China's counter-sanctions. They shape the regulatory environment that determines Illumina's market access. And they hold financial positions in the outcome.
Uber matches the EU's ESMA Short-Selling and Algorithmic Risk Indicators (eu_esma_saris) at 100% confidence. This designation means European financial regulators have placed short-selling restrictions on Uber's securities in European markets. The restriction signals that European regulators consider the stock to carry elevated risk or volatility. It does not imply wrongdoing by Uber, but it does mean that international financial authorities view the company differently than U.S. regulators do.
The Exclusion Lists: When Even Allied Nations Say No
Altria, the tobacco giant, carries two international flags. It matches the EU's ESMA short-selling restriction list (eu_esma_saris) and appears on Norway's Government Pension Fund Global exclusion list (no_nbim_exclusions). Norway's sovereign wealth fund, the largest in the world at over $1.7 trillion, has explicitly excluded Altria from its investment universe on ethical grounds.
When the world's most sophisticated institutional investor, managing more money than the GDP of most countries, decides that a company fails its ethical investment criteria, that decision carries weight. It does not bind anyone else. But it represents a judgment by a government-run fund that buying and holding Altria is incompatible with responsible investment principles. Members of Congress face no comparable ethical screen. They can trade Altria, and any other excluded company, without any system flagging the discrepancy between their investment choices and the standards applied by allied nations' sovereign wealth funds.
The OFAC Match: Iron Mountain
The most legally significant match in the dataset is Iron Mountain. The records management and data storage company matches the U.S. OFAC Specially Designated Nationals list at 70% confidence. The OFAC SDN list is not a foreign counter-sanctions list. It is the United States government's own sanctions list, maintained by the Treasury Department, designating individuals and entities with whom U.S. persons are generally prohibited from doing business.
A 70% match confidence means the entity resolution algorithm found substantial but not conclusive overlap between Iron Mountain's database record and an OFAC SDN entry. This could reflect a partial name match with a different entity, a subsidiary or related entity that carries the designation, or an outdated record that has since been delisted. It is not a definitive determination that Iron Mountain itself is sanctioned by the U.S. government.
But the match exists in the data. And if a compliance department at a bank or brokerage encountered a 70% OFAC match on a client transaction, the transaction would be flagged, reviewed, and potentially blocked until the match was resolved. Congressional stock trades face no equivalent screening. There is no compliance department, no automated flag, and no review process for trades in companies that trigger OFAC matches.
The Strangest Entry in the Database
TV-Novosti, the Russian state-owned media holding company that operates RT (formerly Russia Today), appears in the CapitolExposed database as a FARA-registered foreign principal. It also matches 14 separate sanctions datasets. Fourteen. No other entity in the database comes close to that number.
TV-Novosti is not a company that members of Congress trade. It is a registered foreign agent that spent years operating in the United States under the Foreign Agents Registration Act, lobbying and producing media content designed to influence American public opinion. Its presence in the database illuminates a different facet of the sanctions landscape: the intersection of foreign influence operations and financial networks.
The 14 dataset matches span U.S. sanctions (OFAC), EU sanctions, UK sanctions, Canadian sanctions, Australian sanctions, Japanese sanctions, Swiss sanctions, and several others. TV-Novosti is one of the most sanctioned entities in the world. Its FARA registration, which required it to disclose its activities as an agent of the Russian government, was one of the few transparency mechanisms that actually worked. The company disclosed. Regulators tracked. And eventually, after Russia's invasion of Ukraine, the United States revoked RT's broadcast credentials and added TV-Novosti to multiple sanctions lists.
The contrast with congressional stock trading is instructive. A Russian propaganda outlet was required to register, disclose, and ultimately faced enforcement action. Members of Congress who trade stocks in internationally sanctioned companies face none of those friction points. The system catches foreign agents but not domestic conflicts of interest.
The Structural Problem
The 47 company matches in this analysis represent a category of risk that existing congressional ethics rules do not recognize. The STOCK Act addresses insider trading. Proposed trading bans address the broad conflict between legislating and investing. But neither framework accounts for the international dimension: the fact that some companies members trade carry designations from foreign governments, international regulators, and even the U.S. Treasury Department.
This gap matters because the geopolitical stakes keep rising. U.S.-China tensions over Taiwan, the ongoing conflict in Ukraine, competition with Iran in the Middle East, and the weaponization of financial sanctions as a tool of foreign policy all mean that the companies Congress trades are increasingly entangled in international conflicts. Every vote on defense spending, export controls, or sanctions policy has a downstream effect on the stock price of companies that members hold in their portfolios.
The fix does not require banning all stock trading, though several proposed bills would do exactly that. At minimum, it requires building a screening layer into the disclosure process: an automated check that flags when a member's trade involves a company carrying international sanctions designations, watchlist entries, or regulatory restrictions. Banks do this. Hedge funds do this. Compliance departments at every major financial institution in the world do this. Congress does not.
Methodology
Company sanctions matching uses the OpenSanctions API and bulk dataset, which aggregates sanctions lists, regulatory actions, and watchlist designations from more than 100 official sources worldwide. Match confidence scores reflect the OpenSanctions entity resolution algorithm, which uses name matching, jurisdiction analysis, and entity type classification. Scores above 90% indicate near-certain matches. Scores between 70% and 90% indicate probable matches requiring manual review. FARA data comes from the U.S. Department of Justice FARA registration database. Congressional trading data comes from official Senate and House financial disclosure filings as required by the STOCK Act. All analysis by CapitolExposed.
