Roughly $50 million in federal funding to the University of Maine System has been frozen or terminated by the Trump administration so far, the system said Wednesday, despite previous assurances that funding pauses would be reversed.

The UMaine System’s federal grants have been in limbo since February, when President Donald Trump ordered an investigation into the university system and threatened to pull its grant money following a public spat with Gov. Janet Mills over a Maine state law that allows transgender athletes to compete in girls’ sports.

The Trump administration halted all committed funds to the UMaine System in March before reversing course hours later.

But an internal notice circulated by system officials Wednesday said 23 awards totaling $7.8 million have been terminated and another 19 grants totaling $17 million have been put on pause since Trump’s inauguration in January. Additionally, 10 awards totaling $21 million have been terminated or put on hold as the university was negotiating their terms and conditions, the university system says.

“In some instances, (the University of Maine System) has not received any notice from a federal agency but can no longer access or ‘draw down’ previously awarded funding,” the notice read.

“The system continues to explore avenues of appeal,” the notice continued, noting that $6.2 million in federal grants have been restored so far, including $4.5 million to the Maine Sea Grant, following pressure from members of Maine’s congressional delegation.

Other programs and initiatives, however, are being scaled back because of federal funding cuts and freezes. The Trump administration has gone after higher education funding outside of Maine, too, most notably cutting off $100 million in funding to Harvard University, essentially severing the government’s business relationship with the school.

The UMaine System has been trying to “stave off painful workforce reductions” amid unprecedented financial uncertainty, Board of Trustees Chair Trish Riley said days after financial offers, including teaching and research assistant positions, for graduate students were reinstated after being paused for two months.

Nine employees are set to be laid off from the UMaine Advanced Structures and Composites Center next week “due to disruptions in federal funding, including the suspension of three U.S. Department of Energy awards,” the university system said. The center researches and develops manufacturing and engineering techniques and has received more than 100 patents.

A floating wind turbine that the university was just weeks from launching off the coast of Castine was suspended by the U.S. Department of Energy in April for “failure to comply” with federal policies, though the agency did not specify which ones.

Maine AgrAbility, a program to provide education to farmers and loggers, was abruptly frozen without notice, the system said. All of the program’s scheduled trainings and client workshops have been canceled as a result.

The UMaine System is looking to diversify its funding sources amid the sudden threats to nearly all of its federal grants, spokesperson Samantha Warren said.

“(The system) is actively working with Maine’s congressional delegation, federal agencies, the state of Maine, professional societies, and other key partners to understand impacts, restore funding where possible, and develop strategies for moving forward,” the funding notice read.

Mills has included a 4% increase in state funding to the University of Maine System in her budget proposal, but that still needs legislative approval. The system also has an endowment of more than $400 million, although much of that is set aside of financial aid.
