University of Missouri system President Tim Wolfe resigned Monday amid growing protests from students and faculty that he has not adequately addressed race-related issues on campus, The Associated Press reports. "I take full responsibility for this frustration and I take full responsibility for the inaction that has occurred," he said. "Use my resignation to heal and start talking again." More than 30 football players announced Saturday they would not practice or play in games until Wolfe resigned or was terminated, adding weight to the movement started by a student group in October.
