Maine lawmakers on Thursday sent a draft of gun safety measures to the governor to sign into law, fulfilling a promise to take swift action designed to prevent mass shootings such as a rampage last year that killed 18 people in the city of Lewiston.

Democratic Gov. Janet Mills and the Democratic-led Legislature pressed for a number of gun and mental health proposals after the shooting that claimed 18 lives and injured 13 others, and most were adopted despite the state’s strong hunting tradition and gun ownership.
