美国总统奥巴马在美国的全国假日马丁.路德.金日这一天向马丁.路德.金表达敬意，缅怀这位被刺杀的非洲裔美国人权领袖的一生。
奥巴马和第一夫人米歇尔定于星期一在华盛顿参加一个纪念活动。总统的内阁成员也在全美各地参加纪念仪式和社区活动。
位于亚特兰大的马丁.路德.金中心星期一举行纪念仪式、义工活动和社区项目，使为期一个多星期的纪念活动达到高潮。这个中心把这个联邦假日称为“工作的一天，而不是休息的一天”，即参与社区活动和服务的一天。
马丁.路德.金是一名浸信会牧师。1950和1960年代，他主要在美国南方反抗种族歧视和种族主义。美国南方的黑人当时在社会上受到不平等待遇，并且有时候成为暴力活动的攻击目标。
马丁.路德.金1968年4月4日在田纳西州的孟菲斯被刺杀，享年39岁。
U.S. President Barack Obama is honoring Martin Luther King Jr. during a national holiday celebrating the life of the slain African American civil rights leader.
Mr. Obama and his wife, Michelle, are scheduled to participate in a service event Monday in Washington, while members of the president’s Cabinet attend memorial events and do community service across the nation.
The King Center in Atlanta caps more than a week of events Monday with commemorative ceremonies, volunteer activities and community programs. The center describes the federal holiday as a day to be involved in community events and service — “a day on, not a day off.”
King was a Baptist preacher who fought discrimination and racism in the 1950s and 1960s, mainly in the southern United States, where blacks were subjected to unequal treatment in society and at times the target of violence.
King was assassinated on April 4, 1968, in Memphis, Tennessee. He was 39 years old.
