The week before President Donald Trump unveiled bruising new tariffs that sent the stock market plummeting, a key official in the agency that shapes his administration’s trade policy sold off as much as $30,000 of stock.

Two days before that so-called “Liberation Day” announcement on April 2, a State Department official sold as much as $50,000 in stock, then bought a similar investment as prices fell.

And just before Trump made another significant tariff announcement, a White House lawyer sold shares in nine companies, records show.

More than a dozen high-ranking executive branch officials and congressional aides have made well-timed trades since Trump took office in January, most of them selling stock before the market plunged amid fears that Trump’s tariffs would set off a global trade war, according to a ProPublica review of disclosures across the government.

All of the trades came shortly before a significant government announcement or development that could influence stock prices. Some who sold individual stocks or broader market funds used their earnings to buy investments that are generally less risky, such as bonds or treasuries. Others appear to have kept their money in cash. In one case unrelated to tariffs, records show that a congressional aide bought stock in two mining companies shortly before a key Senate committee approved a bill written by his boss that would help the firms.

Using nonpublic information learned at work to trade securities could violate the law. But even if such actions aren’t influenced by insider knowledge, ethics experts warn that trading stock while the federal government’s actions move markets can create the appearance of impropriety. The recent trades by government officials, they said, underscore that there should be tighter rules on how, or if, federal employees can trade securities.

“The executive branch is routinely engaged in activities that will move the market,” said Tyler Gellasch, who, as a congressional aide, helped write the law on insider trading by government officials and now runs a nonprofit focused on transparency and ethics in capital markets. “I don’t think members of Congress and executive branch officials should be trading securities. To the extent they have investment holdings, it should be managed by someone else outside their purview. The temptation to put their own personal self-interest ahead of their duties to the country is just too high.”

There is no evidence that the trades by government officials identified by ProPublica were informed by nonpublic information. Still, when government officials trade stock at opportune times, Gellasch said, even if it was based on luck and not inside information, it undermines trust in government and the markets

“It then becomes a thing where our markets look rigged,” he said.

In response to questions from ProPublica, the officials who made the trades either said they had no insider information that would help them time their decisions or did not respond to questions about the transactions.

Questions about trades based on nonpublic information have swirled around Congress for years and began anew after Trump’s tariffs announcements led to wild swings in the market. Lawmakers’ trades are automatically posted online and, after multiple congressional stock-trading scandals, are widely scrutinized as soon as they become public.

But less attention is paid to the trades of executive branch employees and congressional aides whose work could give them access to confidential information likely to influence markets once made public.

Last week, ProPublica reported that Attorney General Pam Bondi sold between $1 million and $5 million worth of shares of Trump Media, the president’s social media company, on April 2. After the market closed that day, Trump unveiled his “Liberation Day” tariffs, sending the market reeling. Bondi’s ethics agreement required her to sell by early May, but why she sold on that date is unclear. She has yet to answer questions about the trades, and the Justice Department did not respond to requests for comment.

Earlier this week, ProPublica reported that Sean Duffy, Trump’s transportation secretary, sold shares in almost three dozen companies on Feb. 11, two days before Trump announced plans to institute wide-ranging “reciprocal” tariffs. A Transportation Department spokesperson said Duffy’s account manager made the trades and that Duffy had no input on the timing.

Using insider government information to buy or sell securities could violate the Stop Trading on Congressional Knowledge, or STOCK, Act. But no cases have ever been brought under the law, and some legal experts have doubts it would hold up to scrutiny from the courts, which in recent years have generally narrowed what constitutes illegal insider trading.

Thousands of government employees are required to file disclosure forms if they sell or buy securities worth more than $1,000. In many cases, the records are available only in person in Washington, D.C., or through a records request. The documents do not include exact amounts bought or sold but instead provide a broad range for the totals of each transaction.

ProPublica examined hundreds of records for trades shortly before major tariff announcements or other key government decisions. Trump, of course, repeatedly said on the campaign trail that he intended to institute dramatic tariffs on foreign imports. But during the first weeks of his term, investors were not panic selling, seeming to assume that his campaign promises were bluster. Several tariff announcements by Trump early on shook the markets, but it wasn’t until he detailed his new tariffs on April 2 that stocks dived.

Among those who sold securities before one of Trump’s main tariff announcements was Tobias Dorsey. Dorsey, a lawyer in the executive branch since the Obama administration, was named acting general counsel for the White House’s Office of Administration in January, when Trump was inaugurated. The division provides a range of services, including research and legal counseling across the president’s staff, including the Office of the United States Trade Representative, which helps craft trade policy. In his LinkedIn bio, Dorsey describes his duties since 2022 as giving “expert advice on a wide range of legal and policy matters to help White House officials achieve their policy goals.”

On Feb. 25 and 26, disclosure records show, Dorsey unloaded shares of an index fund and nine companies, including cleaning products manufacturer Clorox and engineering firm Emerson Electric. The total dollar figure for the sales was between $12,000 and $180,000. (He purchased one stock, defense contractor Palantir, which was selling for a bargain after recently plummeting on news of Pentagon budget cuts.)

At the time of Dorsey’s trades, investors were still largely in denial that Trump was going to go through with the massive tariffs he had promised during the campaign. But the next morning, Trump posted on social media that significant tariffs on Mexico and Canada “will, indeed, go into effect, as scheduled” in several days, and that “China will likewise be charged an additional 10% Tariff on that date.”

The S&P 500, a stock index that tracks a wide swath of the market, fell almost 2% that day alone and ultimately dropped nearly 18% in six weeks.

In an interview, Dorsey said the sale was made by his wife from an account belonging to her. He said she decided to sell around $20,000 worth of shares so they could make tuition payments and that he had no nonpublic information on the impending tariff announcements. The kind of work he does as a career employee, he said, focuses not on public policy, but on how the White House operates, including personnel, workplace technology, contracts and records issues.

“I’m not advising Stephen Miller or Peter Navarro,” he said, referring to top policy advisers to the president. “I’m advising the people running the campus. … I don’t have access to any sensitive political information.”

Another well-timed set of transactions was made by Marshall Stallings, the director of intergovernmental affairs and public engagement for Trump’s Trade Representative. The office helps shape the White House’s trade policy and negotiates trade deals with foreign governments.

On March 25 and 27, Stallings sold between $2,000 and $30,000 of stock in retail giant Target and mining company Freeport-McMoRan. The sales appear to have been an abrupt U-turn. He had purchased the shares less than a week earlier. Days after Stallings’ sales, Trump unveiled his most dramatic tariffs. Target stock fell 17%. Freeport-McMoRan fell 25%.

Stallings and the Trade Representative’s office did not respond to multiple requests for comment.

A longtime State Department official, Stephanie Syptak-Ramnath, who until April was ambassador to Peru, also appeared to make a bet against the stock market. On March 24 and 25, she sold between $255,000 and $650,000 in stocks, and bought between $265,000 and $650,000 in bond and treasury funds (along with $50,000 to $100,000 in stocks). Then, on March 31, two days before Trump’s “Liberation Day” announcement, she sold between $15,000 and $50,000 of a broad-based stock fund. When the market started to plummet, she bought back the same dollar range in another stock fund. Syptak-Ramnath said she did not have any information about the administration's decisions beyond what was publicly available. The trades, she said, were “undertaken as a result of family obligations” and in “response to a changing economy.”

A second longtime State Department official, Gautam Rana, who is now ambassador to Slovakia, sold between $830,000 and $1.7 million worth of stock on March 19, a week before Trump declared new tariffs on cars and two weeks before his “Liberation Day” announcement. The shares he sold were largely broad-based index funds. Rana declined to comment for this story.

Virginia Canter, a former government ethics lawyer, said executive branch employees who don’t have nonpublic information and want to trade stock should consult with ethics officials before doing so, thereby allowing an independent third party to assess their actions.

“If you trade and you don’t seek advice in advance, you kind of do it at your own risk, and if you’re asked about it, you have to hope there aren’t factors that make someone question your motivations,” Canter said. “If you seek ethics official advice, you have some cover.”

Executive branch employees are barred from taking government actions that would narrowly benefit them personally, and some are required to sell stock in companies and industries they have purview over in their jobs. But like members of Congress, they are allowed to trade securities.

Since Trump’s tariff announcements and walkbacks began causing fluctuations in the market, questions have been raised about whether anyone has profited off advance notice of the moves. After Trump unexpectedly rolled back some of his tariffs in early April, causing stocks to surge, Rep. Alexandria Ocasio-Cortez warned on social media that “any member of Congress who purchased stocks in the last 48 hours should probably disclose that now.”

Rep. Marjorie Taylor Greene bought between $21,000 and $315,000 of stock the day before and the day of the announcement. In a statement, Greene said a financial adviser controls her investments: “Since my portfolio manager makes my trades for me, I usually find out about them when the media asks.”

ProPublica’s review of disclosures also found trades by congressional aides that took place before the market tumbled.

Michael Platt, a veteran Republican staffer who served in the Commerce Department during Trump’s first term and now works for the House committee that handles administrative matters for the chamber, restructured his portfolio in March. An account under his wife’s name sold off between $96,000 and $390,000 in mostly American companies, and purchased at least $45,000 in foreign stocks and at least $15,000 in an American and Canadian energy index fund. Some stock forecasters considered international markets a relatively safe haven if Trump went through with his tariffs. Platt did not respond to requests for comment.

Stephanie Trifone, a Senate Judiciary Committee aide, sold stock in mid-March and bought at least $50,000 in treasuries. A spokesperson for the committee’s Democratic minority said Trifone had no nonpublic information about the tariffs and her trades were conducted by a financial adviser without her input. Kevin Wheeler, a staffer for the Senate Appropriations Committee, made a similar move. In late February, he and his spouse offloaded between $18,000 and $270,000 in funds composed almost entirely of stocks and bought between $50,000 and $225,000 in bonds. A spokesperson for the Appropriation Committee’s Republican majority said Wheeler had no nonpublic information about Trump’s tariff plans and that a financial planner made the trades after advising Wheeler to take a more conservative approach with his portfolio.

Another staffer, Ryan White, chief of staff to Sen. James Risch, R-Idaho, bought shares worth between $2,000 and $30,000 in two precious metals mining companies two days before Trump’s “Liberation Day” announcement. He continued buying more shares in the companies, Hecla Mining and Coeur Mining, in the following days.
