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.

• 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.
• US Rep. Marjorie Taylor Greene bought between $21,000 and $315,000 of stock the day before and the day of the announcement.
• Transportation Secretary Sean Duffy, sold shares in almost three dozen companies on Feb. 11, two days before Trump announced plans to institute wide-ranging “reciprocal” tariffs.
• Acting General Council for the White House Tobias Dorsey sold shares of an index fund and nine companies, including cleaning products manufacturer Clorox and engineering firm Emerson Electric the day before the tariffs were confirmed.
• The Trade Representative's, Director for Intergovernmental Affairs and Public Engagement Marshall 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.
• A longtime State Department official, Stephanie Syptak-Ramnath, who until April was ambassador to Peru, 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). She continued to play the market through the news.
• 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.
• 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 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. He used an account under his wife's name.
• Stephanie Trifone, a Senate Judiciary Committee aide, sold stock in mid-March and bought at least $50,000 in treasuries.
• 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.
• 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. Also, a bill White’s boss introduced to make it easier for mining companies like Hecla and Coeur to operate on public lands was approved by a Senate committee, an important step in passing a bill. (White added to his Hecla shares earlier this month and sold his stake in Coeur.)
