and endorsed a book questioning Kerry's service record and his military awards. The group included several members of Kerry's unit, such as Larry Thurlow, who commanded a swift boat alongside of Kerry's, and Stephen Gardner, who served on Kerry's boat. The campaign inspired the widely used political pejorative '"swiftboating," to describe an unfair or untrue political attack. Most of Kerry's former crewmates have stated that SBVT's allegations are false. Anti-war activism (1970–1971) After returning to the United States, Kerry moved to Waltham, Massachusetts and joined the Vietnam Veterans Against the War (VVAW). Then numbering about 20,000, VVAW was considered by some (including the administration of President Richard Nixon) to be an effective, if controversial, component of the antiwar movement. Kerry participated in the "Winter Soldier Investigation" conducted by VVAW of U.S. atrocities in Vietnam, and he appears in a film by that name that documents the investigation. According to Nixon Secretary of Defense Melvin Laird, "I didn't approve of what he did, but I understood the protesters quite well", and he declined two requests from the Navy to court martial Reserve Lieutenant Kerry over his antiwar activity. On April 22, 1971, Kerry appeared before a U.S. Senate committee hearing on proposals relating to ending the war. The day after this testimony, Kerry participated in a demonstration with thousands of other veterans in which he and other Vietnam War veterans threw their medals and service ribbons over a fence erected at the front steps of the United States Capitol building to dramatize their opposition to the war. Jack Smith, a Marine, read a statement explaining why the veterans were returning their military awards to the government. For more than two hours, almost 1,000 angry veterans tossed their medals, ribbons, hats, jackets, and military papers over the fence. Each veteran gave his or her name, hometown, branch of service and a statement. Kerry threw some of his own decorations and awards as well as some given to him by other veterans to throw. As Kerry threw his decorations over the fence, his statement was: "I'm not doing this for any violent reasons, but for peace and justice, and to try and make this country wake up once and for all." Kerry was arrested on May 30, 1971, during a VVAW march to honor American POWs held captive by North Vietnam. The march was planned as a multi-day event from Concord to Boston,
