Sen. John Fetterman pushed to ban family stock trades. His family just bought Micron stock — it got $6.1B from a program his own committee oversees

But recent disclosures show that trades are still happening in lawmakers' households — including Fetterman (2) — and he's far from alone.

A filing dated April 3, 2026, indicates that a "child" of Sen. Fetterman purchased between $1,001 and $15,000 of Micron Technology stock on March 30, 2026 (3). The filing also shows a "child" purchased shares in Microsoft, Alphabet, Amazon.com and Erie Indemnity.

Sen. Fetterman is a member of the Committee on Commerce, Science and Transportation (4), which oversees the implementation of the CHIPS and Science Act (5) — a program that awarded Micron Technology $6.165 billion to build chip factories (6).

Fetterman was also one of four lawmakers — three of whom sit on the Commerce, Science and Transportation Committee — who reported personal or family purchases of AI stock while the Senate was considering the deregulation of AI last year (7).

Lawmakers can still trade stocks tied to their work

Under the Stop Trading on Congressional Knowledge (STOCK) Act of 2012, members of Congress and their immediate families are prohibited from using non-public information to make investment decisions. They must also disclose their purchases (8).

While it's not illegal for lawmakers to trade stocks, issues can arise when they trade stocks related to their work.

Indeed, after suspicious trading on prediction markets just minutes before critical announcements on the war in Iran, the White House issued a directive last month against using insider information to bet on financial markets (9).

Stock trading by Congress remains widespread

Based on reports filed in 2024, only 5% of senators and representatives didn't own stock (10). And a recent CNN report found that at least nine senators had bought or sold stock in companies that were overseen by industry committees they serve (11).

"It's a bipartisan problem. Republicans and Democrats are guilty of this, pretty evenly across the board," Dylan Hedtler-Gaudette, acting vice-president of the Project on Government Oversight, told CNN (11).

The absence of stronger rules — and weak consequences for breaking them — has "led to repeated examples of ethical violations and questionable financial activity, including during the tariff announcements in 2025 and global health emergencies in 2020," according to the Campaign Legal Center (CLC) (12).

During the 2025 government shutdown that resulted in "missed paychecks and drained SNAP benefits," CLC reports that the country's lawmakers "engaged in nearly 200 trades, representing anywhere from $3 to $9 million in financial assets."

There's also some evidence that stocks purchased by senators could be "driven by superior information," according to research published in the Journal of Business Ethics (13).

The research found that stocks purchased by senators outperformed the market over a three-month period following the date of the trade, with an "abnormal return" that exceeds the return of the S&P 500. The data implies that "many more people are trading around these dates, likely on the same congressional knowledge."

Why critics say current rules fall short

When lawmakers buy stocks in companies they regulate, it can create serious conflicts of interest. For example, they could influence policy in a way that would benefit their pocketbook rather than the public good. It could also lead to insider trading.

"Lawmakers often have access to non-public information that can move financial markets, as well as the power to shape policies in sectors in which they have financial interests," according to the Brennan Center for Justice (14).
