PORTLAND, Maine (AP) A group of senators including Republican Sen. Susan Collins of Maine has proposed a law it said would make certain first responders get full retirement benefits if they're injured on the job. Collins is working on the proposal with Democratic Sens. Jon Tester of Montana and Kirsten Gillibrand of New York. The group said the First Responders Fair Return for Employees on Their Initial Retirement Earned Act, or the RETIRE.
