Hundreds of students led by the head of the Columbia Faculty union confronted Columbia President and CEO Kwang-Wu Kim on Saturday, Oct. 21, demanding that he step down amid growing concerns over measures the college is taking to close a $20 million deficit, including increasing class sizes. The students, along with Diana Vallera, president of the Columbia College Faculty Union, which is currently in contract negotiations with the college, took over a president’s brunch at the Student Center that was part of Family Weekend.
