Gov. Janet Mills, a Democratic candidate for the U.S. Senate, has filed a personal financial disclosure detailing more than $170,000 in stock investments. This comes amid a bipartisan push to ban stock trading by members of Congress. Mills said she supports efforts to ban congressional stock trading and would place her investments in a blind trust if elected to the Senate.

Why it matters

The disclosure of Mills' stock holdings highlights the ongoing debate over whether members of Congress should be allowed to trade individual stocks while in office. This issue has become a key point of contention in the U.S. Senate race in Maine, with Mills criticizing her Republican opponent, Sen. Susan Collins, for opposing a bill to ban congressional stock trading.

The details

Mills' financial disclosure covers the 22-month period prior to her entry into the Senate race in October 2025. It shows she holds between $169,000 and $460,000 in stocks, with more than half of that in Microsoft. She also has investments in Home Depot, Boston Scientific, Bank of America, Bristol-Myers Squibb, and Pfizer. In contrast, her primary opponent, Graham Platner, did not report any individual stock holdings in his disclosure.

  • Mills filed her personal financial disclosure on February 11, 2026 after receiving a 90-day extension last fall.
  • The disclosure covers the 22-month period preceding her entry into the U.S. Senate race in October 2025.

What they’re saying

“Unlike Susan Collins, I will fully support legislation to ban Congressional stock trading. The people of Maine and America deserve to know their leaders in Congress are focused on one thing and one thing only: advancing the interests of the people they're elected to serve — and that is exactly what they will get with me.”

— Janet Mills, Governor of Maine (pressherald.com)

“Senator Collins has never bought, sold, or owned any shares of stock during her entire Senate tenure.”
