Resurrection City was stunned when Robert F. Kennedy was assassinated on June 5; many took this second killing as a sign of bad things to come. Kennedy's funeral procession passed through Resurrection City en route to Arlington National Cemetery and many residents joined the group in singing "The Battle Hymn of the Republic" at the Lincoln Memorial. Hawthorne School Some marchers, including the grand majority of Chicano activists, chose to live in the Hawthorne School, an alternative high school in D.C. a few miles away from Resurrection City. Not only did the school offer dry conditions, in contrast to Resurrection City, it also witnessed interesting interactions between people of different backgrounds. Residents referred to it as a tight-knit community in which cultural exchange flourished between Chicanos, poor Appalachian whites, and other folks escaping the poor weather. It was also from Hawthorne where protesters marched to the Supreme Court and held one of the campaign's most captivating protests. Opposed to a recent court ruling on native fishing rights, the mostly African-American, Chicano, and Native American protesters pounded on the court's front doors and received considerable media attention. Solidarity Day A Solidarity Day rally, initially planned for May 30, was postponed by Abernathy, who asked Bayard Rustin to organize the rescheduled event. On June 8, however, it was announced that Rustin had been dropped from the Poor People's Campaign following a fallout with Ralph Abernathy, who believed Rustin's proposal for an Economic Bill of Rights ignored many issues important to SCLC's campaign partners, including opposition to the Vietnam War. Following Rustin's departure, SCLC leaders agreed to appoint Washington Urban League Director Sterling Tucker, who was relatively unknown outside the Washington metro area, to lead the Solidarity Day march. Solidarity Day was ultimately held on Wednesday, June 19 (Juneteenth), and attracted between 50,000 and 100,000 people (including many whites). The crowd was addressed not only by SCLC leaders—including Abernathy and Coretta Scott King (who spoke against the Vietnam War)—but also by Tijerina, Native American activist Martha Grass, and politicians such as Eugene McCarthy (whom they applauded) and Hubert Humphrey (whom they booed). In addition, Walter Reuther, president of the United Auto Workers, gave a speech to the assembled crowd. Under Reuther's leadership, the UAW brought 80 busloads of union members to the event, representing the largest contingent from any organization. Puerto Rican and Chicano marchers held a separate rally on the weekend before
