Democratic Rep. Seth Moulton of Massachusetts is seeking the Democratic nomination for president in 2020. As a retired Marine who served four tours in Iraq, Moulton publicly revealed he sought counseling after his deployments. Moulton, 40, unveiled a plan to combat post-traumatic stress in the military with “mandatory” mental health services for veterans and those currently serving.

While his website outlines seven main issues, Moulton’s campaign bundles several of his policies, including climate change and reduced college tuition, into one plan: a new public service program that expands national service participation – from serving in the military to the creation of a Federal Green Corps. In exchange for young Americans’ service, the federal government will provide education benefits that echoes the G.I. Bill.
