served from 1968 until stepping down to join the faculty June 6, 1977, when former Governor Daniel J. Evans, who signed the legislation creating Evergreen, assumed the presidency. Evans left the president's office in 1983 when he was appointed to the United States Senate to fill the vacancy created by the death of Senator Henry M. Jackson. The largest building on campus is named in honor of Evans, the Daniel J. Evans Library Building. The entrance to the campus bears McCann's name, the Charles J. McCann plaza. In the 1992–93 school year, students chose Leonard Peltier to give the address at commencement, which was the first with a graduating class of more than 1,000. The selection was described as "perhaps the most unconventional commencement speaker" in a published round-up of the most controversial graduation speakers on campuses nationwide that year. Peltier, who was in federal prison, submitted his remarks in writing, to be read by a graduating senior. In 1999, Mumia Abu-Jamal was invited to deliver the keynote address by audiotape for the graduating class at the college. The event was protested by some. In 2004, the college completed the Seminar II building, as well as a significant remodeling of the Daniel J Evans Library. In 2015, George Sumner Bridges became the sixth president of Evergreen State College, not counting interim appointments. Bridges had previously served as president of Whitman College in Walla Walla, Washington. He followed Thomas L. "Les" Purce (2000–2015), Jane L. Jervis (1992–2000), and Joseph D. Olander (1985–1990). 2017 protests President Bridges appointed a committee to study social equity on campus. In November 2016, the committee recommended changes to faculty hiring and evaluation criteria that proved to be controversial. The debate continued through the spring quarter. Every April from the 1970s until 2017, Evergreen held a daylong event called "Day of Absence", inspired by the Douglas Turner Ward play of the same name, during which minority students and faculty members voluntarily stayed off campus to raise awareness of the contributions of minorities and to discuss racial and campus issues. Since 1992, the Day of Absence has been followed by the "Day of Presence", when the campus community reunites. In 2017, approximately 25% of Evergreen students were members of racial minority groups. In 2017, some students of color voiced concerns about feeling unwelcome on campus following the 2016 US presidential election and a 2015 off-campus police shooting. Consequently,
