Obama takes aim at himself with caustic humour

US President Barack Obama poked fun at himself and what he called a hard year but aimed his most caustic humour at Washington gridlock when the political and media elites gathered at the annual White House Correspondents’ Association dinner.

“In 2008 my slogan was, ‘Yes we can.’ In 2013, it was control-alt-delete,” Obama joked to an audience studded with film and television stars.
