RFK Stadium Robert F. Kennedy Memorial Stadium, better known as RFK Stadium or RFK, is a multi-purpose stadium in Washington, D.C., United States, and the current home of Major League Soccer's D.C. United. Opened in October 1961 as District of Columbia Stadium (D.C. Stadium for short), RFK was the home of the NFL's Washington Redskins for 36 seasons, from 1961 through 1996. RFK Stadium also served as the home to the expansion Washington Senators of the American League from 1962 through 1971. The National League's Montreal Expos relocated to Washington as the Washington Nationals in 2005 and played at RFK through 2007; the club has since moved to Nationals Park, which opened in 2008. Rock concerts have also taken place at the stadium. It has hosted international soccer matches in the 1994 FIFA World Cup, 1996 Summer Olympics and 2003 Women's World Cup. The stadium was renamed in January 1969 for U.S. Senator and presidential candidate Robert F. Kennedy, who had been assassinated in Los Angeles the previous June. As Attorney General, Kennedy's Justice Department played a role in the racial integration of the Redskins. Along with Secretary of the Interior Stewart Udall, Kennedy threatened to revoke the team's lease at the federally-owned stadium until it promised to sign African American players. RFK was the first major stadium designed specifically as a multisport facility for both football and baseball. During the Nationals' tenure at the stadium, it was the fourth-oldest active stadium in Major League Baseball behind Fenway Park, Wrigley Field and Yankee Stadium (1923).
