Maine Governor Janet Mills: New Laws and Data Center Veto

Maine Governor Janet Mills was involved in two distinct actions reported separately: the rollout of new state laws and a veto of data center legislation. The new laws, described by the Governor's office, include a Supplemental Budget that builds on housing investments, adding over 400 new affordable homes, extending an affordable housing tax credit, and limiting rent increases on mobile homes. Separately, on April 25, 2026, NBC News reported that Mills vetoed a bill that would have banned certain data center construction in Maine. According to NBC News, Mills cited the bill's failure to exempt a specific project in Jay, Maine, which she said was expected to create more than 800 construction jobs and at least 100 permanent jobs, as her reason for the veto. NBC News also reported that Mills is currently running for U.S. Senate and is in a primary race against progressive rival Graham Platner, who publicly stated she should have signed the bill rather than veto it. The housing-related laws were reported by the Governor's office without independent corroboration of specific figures such as the number of affordable homes or the scope of the tax credit extension. The current status of both matters is that the laws described by the Governor's office have taken effect, and the data center bill has been vetoed, according to available reporting. It remains unresolved whether the Maine Legislature will attempt to override the veto or pursue revised legislation addressing the Jay project exemption. The broader political context, including how the veto may affect the Senate primary between Mills and Platner, is noted by NBC News but not independently verified by additional sourcing.
