Maine lawmakers approved several notable measures during the 132nd legislative session, including a bill giving jails more say in accepting people detained solely on civil immigration violations, a requirement for political ads made with artificial intelligence to disclose that fact, and increased funding for housing and rent relief programs. However, other proposals such as digital privacy legislation and a pilot program for speed cameras in highway work zones failed to pass.

Why it matters

This was the final legislative session under Governor Janet Mills, who has seen Democrats control the Legislature for her entire eight-year tenure. The November elections could reshape the political landscape, with Maine historically flip-flopping between Republican and Democratic governors.

The details

Key bills that passed include LD 2058, which gives jails more discretion on accepting people detained solely on civil immigration violations, and LD 517, which requires disclosure labels for political ads made with artificial intelligence. The Legislature also approved increased funding for housing and rent relief programs in the supplemental budget. However, proposals like a digital privacy bill and a work zone speed camera pilot program were defeated.

  • The legislative session concluded on April 15, 2026.
  • Governor Mills has 10 days to sign, veto, or allow bills to become law without her signature.
  • Most new laws will take effect in late July 2026, 90 days after the Legislature adjourns.

What they’re saying

“Using artificial intelligence in political ads deliberately deceives voters and intentionally creates distrust in our elections. Requiring campaigns to disclose when something isn't real will help increase transparency for voters.”

— Amy Kuhn, Representative

What’s next

Governor Mills has until April 29 to take action on any bills passed by the Legislature, including deciding whether to sign or veto the proposal for a temporary moratorium on new data centers.

The takeaway

The final legislative session under Governor Mills saw a mix of bills passed and defeated, reflecting the shifting political landscape in Maine as the state prepares for a new gubernatorial election. The measures approved on immigration, AI disclosure, and housing funding highlight the key policy debates that will likely continue to shape the state's future.
