On Nov. 22, 1963, while on a campaign trip to Dallas, President Kennedy was shot and killed. There are only two U.S. presidents buried at Arlington National Cemetery. The other is William Howard Taft, who died in 1930. Though Kennedy is buried at Arlington, at the time of his death, many believed that he would be buried in Brookline, Mass. Woodrow Wilson was the only other president besides Taft who had been buried outside of his native state and in the National Capital Region.
