Obama mourns passing of Robin Williams, calls him 'one of a kind'
- President Barack Obama speaks Monday, Aug. 11, 2014, in Chilmark, Mass., during his family vacation on the island of Martha's Vineyard.
Williams was pronounced dead at his home in California Monday and officials said it appeared to be a suicide.
Obama said in a statement issued Monday night that Williams "arrived in our lives as an alien - but he ended up touching every element of the human spirit," referring to Williams' late 1970s role in the TV show "Mork and Mindy."
The president said the actor was generous with his comic talents for those who needed it, including troops abroad.
The statement said: "The Obama family offers our condolences to Robin's family, his friends, and everyone who found their voice and their verse thanks to Robin Williams."
