Obamas celebrate King's birthday
President Barack Obama and his family have celebrated Martin Luther King Jr's birthday at a morning worship service.
Mr Obama, his wife Michelle, and daughters Sasha and Malia sat in the second row of Washington's historic Zion Baptist Church, as bright sunlight streamed through stained-glass windows.
The church commemorated the slain civil rights leader's 83rd birthday with a photo of King on the steps of the Lincoln Memorial and the words "I Have a Dream" on the programme cover.
A deacon welcomed the first family and read a passage from King's Letter from a Birmingham Jail.
The sermon by Rev Keith Byrd came from Matthew 5, which describes the salt of the earth.
He urged the congregation to "preserve our morals, preserve our values" like salt amid political, social and economic turmoil.
