The Boston College Carroll School of Management’s Winston Center for Leadership and Ethics will host an appearance and book signing by former US Senator Olympia Snowe on Feb. 11 at 7 p.m. in Gasson Hall, room 100. During her 18 years in the Senate, Snowe earned a reputation as one of the Congress’ leading moderates and as a policymaker who focused on efforts to build bipartisan consensus on key issues. She is the author of the book, Fighting for Common Ground: How We Can Fix The Stalemate in Congress (Weinstein Publishing). During her time in the Senate, Snowe worked extensively on a number of issues, such as budget and fiscal responsibility; education, including student financial aid and education technology; national security; women’s issues; health care, including prescription drug coverage for Medicare recipients; welfare reform; oceans and fisheries issues; and campaign finance reform. The Winston Center event is free and open to the public. Doors open at 6:45 p.m. Snowe’s book will be on sale at a 20 percent discount.
