ST. PAUL — Minnesota State Colleges and Universities presidents and trustees are vocalizing their support for the system’s chancellor while faculty and some student groups continue to question his leadership.

Opponents said Chancellor Steven Rosenstone’s collaboration plan for the system’s 31 schools had little input from faculty and students. They were not informed of a $2 million consulting contract with New York-based McKinsey & Co. which helped develop the plan.

MnSCU presidents said “there are difficult questions of sustainability” facing the institutions. Trustees board chairman Tom Renier is urging faculty groups to take Rosenstone up on his offer to mediate their dispute over the system’s future.

Faculty members from all seven universities have voted “no confidence” in Rosenstone and have stopped deliberating on his collaboration plan.
