Martin Luther King's Legacy

On the 50th anniversary of the assassination of Martin Luther King Jr, we'll have a live debate on race relations, and look at the racial make up of the US Congress.
Also today; speculation about the motives of the suspect in a gun attack at YouTube's HQ in California. The latest from the Hague where the world’s chemical weapons watchdog is meeting to discuss the poisoning of a former Russian spy and his daughter in the UK. And a man,who posts photographs of himself in front of famous landmarks with his handmade sweaters.
