A coalition of 25 states, including Wisconsin, sued the Trump administration Tuesday to block the cancellation of AmeriCorps programs across the country.

The cancellation has upended plans at more than two dozen organizations in Wisconsin that have engaged AmeriCorps members in community service work, and stranded scores of participants in the midst of one-year stints in the program.

“I was completely blindsided,” Parker Kuehni told the Wisconsin Examiner on Tuesday. The University of Wisconsin-Madison graduate with a degree in global health was in his second year with AmeriCorps, working at a Madison free health clinic and preparing to start medical school in June when he learned Monday morning that the program was canceled.

Created by Congress in 1993 as the Corporation for National and Community Service, its official name, AmeriCorps has deployed community service workers across the country in the decades since. AmeriCorps members are usually recent college graduates who join the program for a year or two. They teach in schools, assist with disaster relief and take on a host of other roles.
