The Springfield Museums will welcome state Sen. Eric Lesser on Monday, Oct. 25 at 11 a.m. to announce a $100,000 earmark from the Commonwealth to help fund the International Space Station exhibit in the Springfield Science Museum. The public is welcome to attend this announcement on the Quadrangle green. Earmarks from the Commonwealth are a source of funding outside the normal budgeting process for specific programs and services. Elected officials sponsor and advocate for earmarks to benefit their constituents. Gov. Charlie Baker approves, rejects, or amends earmarks as needed.
