Former provost Scott Coltrane served as interim president, from August 6, 2014, through June 30, 2015, following the resignation of Michael Gottfredson. This resignation occurred with less than 24 hours notice amidst a number of controversies, including allegations of mishandling of sexual violence, a decline of $100 million in university donations, and the alienation of faculty members around unionization and academic freedom. Including one interim president, Gottfredson was the university's fourth president in six years, a situation that led Chronicle of Higher Education to label the position a "revolving door."
