Troubled Hollywood star Charlie Sheen has launched a bizarre, racist Twitter rant at Barack Obama where he calls the President 'Barry Satera Kenya'.

The actor wrongly accused President Obama of failing to send official representation to the funeral of Major General Harold Greene who was killed in Afghanistan in 2014.
