The American Enterprise Institute, a prominent conservative-leaning think tank, has named former U.S. senator and university president Ben Sasse a nonresident senior fellow, AEI announced Friday. Its website says his work there will focus on “higher education, innovation, technology, American history and culture, and national security.”

Sasse’s AEI post and his continuing voice at other major conservative institutions—The Wall Street Journal has run at least three op-eds by him this year, including one calling on university board members across the country to stand up to faculty “radicals” and “encourage greater intellectual diversity”—shows he’s not persona non grata after his abrupt exit from the University of Florida last year.

Sasse attributed his resignation from UF to his wife’s health, though the student newspaper, The Independent Florida Alligator, has reported the board may have forced him out. During the first year of his roughly 18-month presidency, his office spent more than $17 million. Sasse denied wrongdoing and argued that driving new initiatives at UF required major investments.

Sasse, a Republican who represented Nebraska in the Senate, remains a professor in UF’s Hamilton Center for Classical and Civic Education. He previously was president of Midland University.
