Governor Janet Mills has unveiled the second part of her budget proposal, which she says would cover more than half the costs for local schools to operate.

On Wednesday, the governor’s office said the proposal would pay 55% of costs for K-12 public schooling, more than fifteen years after voters approved a referendum requiring state government to cover that amount.

The budget proposal, which the governor’s office says would not raise taxes, builds on her original proposal for the 2022-2023 budget, and if approved, would result in an $8.7 billion biennium budget.

The plan sets aside millions of dollars each for things like MaineCare reform, economic relief for low- and middle-income people, and infrastructure.

Governor Mills says this latest proposal would deposit another $52 million in the state’s rainy day fund, growing it to nearly $320 million.
