Congress seeks answers about deals linked to Trump’s circle, investigation also takes on an international dimension
A new investigation in the United States House of Representatives is further intensifying political pressure on President Donald Trump and people from his business environment. At the center of interest are possible cases of insider trading, suspicions of market manipulation, and questions as to whether American regulators reacted too slowly or not decisively enough at moments when White House political decisions strongly moved the stock markets. As issues involving Chinese companies on the American capital market, audit oversight, and the ties of certain investors to Trump’s business projects are also opening up in parallel, the case is looking less and less like an isolated political conflict and more and more like a broader test of the American system of oversight over financial markets.
The most concrete move came on February 24, 2026, when the leading Democrat on the Financial Services Committee, Maxine Waters, and Representative Al Green asked committee chairman French Hill to launch an official congressional investigation. In the letter, they warn of possible illegal actions linked to the period from April 6 to 9, 2025, when, according to their interpretation, there was an opportunity at the top of the administration to obtain and possibly exploit market-sensitive, non-public information about Trump’s decision to temporarily halt part of the previously announced tariffs. Democrats claim that almost a year after their first requests to regulators, they have not received a substantive response, which is why they are now demanding that Congress itself take on a more active role.
What triggered the new investigation
The background of the entire case dates back to early April 2025, when the Trump administration caused a sharp decline in the markets with aggressive tariff announcements. The letter from congressional Democrats states that U.S. Treasury Secretary Scott Bessent visited Trump at his resort in Florida on April 6, 2025, and three days later the president announced a postponement of part of the tariffs. Several hours before that announcement, Trump wrote on the social network Truth Social that it was a “great time to buy,” along with the label “DJT,” which is also the stock ticker of his media company. This was followed by a sharp market jump: according to an Associated Press report, the S&P 500 rose by 9.5 percent on April 9, 2025, the Dow Jones by almost 3,000 points, and the Nasdaq by more than 12 percent.
It is precisely that sequence of events that forms the core of the political and legal doubts. Critics argue that it must be established whether anyone from the administration, from Trump’s business circle, or among investors close to him knew in advance that part of the tariffs would be paused and whether they traded stocks or other financial instruments on that basis. At the same time, Democrats do not claim that criminal liability has already been proven, but they insist that even the appearance of possible favoritism sufficiently undermines confidence in the market and state institutions. In their argumentation, it is especially important that these are presidential decisions that are themselves capable of erasing or creating enormous amounts of market value within a few hours.
The letter sent to the Financial Services Committee is therefore not formulated as a routine political attack, but as a request to verify whether insider trading, market manipulation, or other forms of abuse occurred. Waters and Green ask the committee to examine whether any persons or entities, regardless of whether they are registered with the Securities and Exchange Commission, used information about the upcoming tariff decision before it became public. If elements of a criminal offense were found, they request that the case be referred to the Department of Justice.
Why the issue does not stop only at tariffs
Although the latest congressional initiative is tied to the tariff reversal from April 2025, the political problem for Trump’s circle does not end with that episode. For months, Democrats have been trying to show a pattern in which major political decisions, from trade policy to crypto regulation and foreign policy, intertwine with the private business interests of people connected to the president. That is why people in Washington are increasingly speaking of a “systemic pattern,” and not of a single incident.
Additional weight to that thesis is given by the fact that similar suspicions have also emerged in other areas. At the beginning of 2026, Maxine Waters opened another investigation, this time into possible financial irregularities after Trump’s military action connected to Venezuela, explicitly warning of what she described as a “known pattern” in which suspicious market activity follows sensitive political decisions. This context is important because it shows that Democrats are not treating the tariff case as an isolated event, but as part of a broader story about whether presidential power is being used to create financial opportunities for a narrow circle of politically connected actors.
In an election year, such accusations carry particular weight. Even when they do not end in a court outcome, they can become a powerful political weapon because they offer the public an easily understandable framework: those who decide on the rules may at the same time be profiting from the consequences of their own decisions. That is precisely why investigations in Congress rarely remain only a technical question of regulators’ jurisdiction. They turn into a dispute about the credibility of the government, equality of access to the market, and the boundaries between public office and private profit.
The Chinese dimension: from capital markets to national security
The international dimension of the story comes from two directions. The first relates to long-standing American doubts about the presence of Chinese companies on American stock exchanges and the level of audit oversight over their operations. The chairman of the House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party, John Moolenaar, and Senator Rick Scott already requested an urgent briefing in July 2025 from the Securities and Exchange Commission and the PCAOB on the risks posed to American investors by Chinese companies listed in the United States. They warned that, despite the 2022 agreement between Chinese regulators and the PCAOB, serious gaps in transparency and regulatory oversight still exist.
This is important background because it shows that the issue of Chinese securities issuers is not a fringe topic, but part of a broader American security and financial dispute. The Holding Foreign Companies Accountable Act, a U.S. law adopted in 2020, provides for the delisting of foreign companies whose audits the PCAOB cannot fully inspect for two consecutive years. On its official website, the SEC reminds readers that in December 2022 the PCAOB withdrew its earlier determinations about the inability to conduct complete inspections in China and Hong Kong, but political pressure has not disappeared. In Congress, there is still a strong current that believes American investors are not sufficiently protected when it comes to companies linked to the Chinese regulatory and political system.
The second direction of the international dimension is linked to cryptocurrencies and Justin Sun, a Chinese-born entrepreneur from the crypto sector, whose name has appeared several times in recent months in congressional and regulatory documents. Democratic members of Congress, including Sean Casten and Senator Jeff Merkley, already requested heightened SEC oversight in 2025 of Sun’s business dealings and his ties to Trump’s crypto projects. In the letter, they warned that Sun invested tens of millions of dollars in World Liberty Financial, a project backed by Trump and members of his family, and that after such investments there was a shift in the regulatory treatment of his case.
Justin Sun, Tron, and the question of regulatory criteria
Congressional interest in Justin Sun has been further intensified by his plans to take the company Tron to the American capital market through a reverse merger transaction. In the memorandum by Casten and Merkley, it is stated that the deal, worth around 210 million dollars, was carried out through SRM Entertainment, which was then renamed Tron Inc., while Dominari Securities, an investment firm headquartered in Trump Tower, is mentioned as an intermediary; Donald Trump Jr. and Eric Trump sit on its advisory board. It is precisely that combination of a Chinese-born crypto entrepreneur, Trump’s family business network, and entry onto the American capital market through a simplified listing model that has created a politically explosive combination.
A reverse merger is not in itself an illegal mechanism, but in American regulatory and political memory it carries a sensitive burden. Critics recall that it was precisely such structures that in the past decade were associated with a series of frauds and accounting problems involving some Chinese companies that reached American exchanges outside the classic IPO process. In the congressmen’s memorandum to the SEC, it is explicitly stated that Chinese companies in the period from 2007 to 2010, through reverse merger processes, caused enormous losses to American investors, which is why strict oversight criteria for similar deals are still being demanded today.
In the whole story, additional political sensitivity is also created by the change in the SEC’s own proceeding against Sun. Back in 2023, the Commission sued him and related entities for allegedly orchestrating a scheme that artificially inflated the activity and price of the TRX token, along with millions in unlawful proceeds according to the regulator’s allegations at the time. On the SEC’s official website, it is now visible that on March 5, 2026, a new procedural step was published in the case against Sun and related companies, including an amended complaint and a proposed settlement for part of the defendants. On the same day, Senator Elizabeth Warren said that the SEC’s decision to drop part of the case against Sun raises serious questions about whether persons linked to Trump’s business interests are receiving more lenient regulatory treatment.
For Trump’s opponents, the problem is not only whether Sun broke the rules, but also what picture is created by the connection between private investments in the president’s projects and subsequent regulatory decisions. For Trump’s side, such accusations are politically motivated and based on insinuations rather than on legally established facts. But it is precisely that gap between the formal legal standard and political perception that keeps the issue alive: in Washington, it is enough for a suspicion to arise that access to the regulator or the White House was made easier for those who at the same time do business with the president’s family.
Regulators under pressure and the question of the system’s credibility
Besides Trump and business actors close to him, the regulators themselves are also under pressure. Democrats in Congress openly say that the problem also lies in possible failures by the SEC, that is, in the slowness and indecision of the institutions that should be the first protective mechanism of market integrity. The Waters and Green letter states that almost a year has passed since their first request in April 2025 without a substantive response, while SEC Chairman Paul Atkins, at a hearing in February 2026, according to that memorandum, appeared insufficiently familiar with the entire case. In this way, the political focus expands from the question “who may have profited” to the equally important question “why the system did not give a clear answer earlier.”
In the American financial system, the credibility of regulators is almost as important as criminal prosecution. Markets rest on the assumption that all participants have fair access to publicly available information and that those with privileged positions cannot profit with impunity from information unknown to others. When a suspicion appears that political power brokers or their business partners may have received different treatment, that becomes a question of institutional stability and not merely of day-to-day politics.
That is why this investigation also has broader consequences. If Congress concludes that there were serious failures in oversight, new hearings could follow, requests for documents, calls for regulators to tighten criteria, and additional pressure for rule changes in the areas of conflicts of interest, market manipulation, and crypto assets. If, however, the investigation does not produce solid evidence, Trump and his allies will gain room to argue that this is yet another politically motivated campaign by Democrats. In both scenarios, the political damage or benefit will depend not only on the final legal outcome, but also on who shapes the public narrative more convincingly.
What comes next in Washington
According to the currently available information, the new Democratic request does not automatically mean the formal opening of a full investigation with binding powers, but it does intensify pressure on the Republican leadership of the committee to react. But the very fact that in the same political space the topics of tariff policy, market jumps, regulatory responses, Chinese companies on American exchanges, and crypto deals linked to Trump’s family are now overlapping indicates that a longer-term dispute is opening up before Washington. That dispute is important not only because of the fate of individuals, but also because it shows how, in contemporary American politics, the boundaries between national security, financial markets, digital assets, and electoral struggle are becoming increasingly difficult to separate clearly.
For a reader outside the United States, it is especially important to understand that this is more than just another episode in American partisan bickering. When Congress simultaneously questions possible insider information trading, the access of Chinese companies to American capital, and the regulatory relationship toward investors who do business with the president’s circle, this is an issue that affects global confidence in the world’s largest capital market. The outcome may not arrive quickly, but the political and institutional stakes are already high: every new disclosure, every document, and every hearing can further determine how the public will assess the relationship between political power and private money in Trump’s America.
