Actor and Democratic donor George Clooney has urged Joe Biden to drop out of the presidential race.  

All eyes have been on Biden at the NATO summit in Washington DC.  

Nancy Pelosi says time is running short for him to make a decision.  

US correspondent Katherine Firkin told Ryan Bridge Clooney has written an essay in the New York Times saying they need a new nominee.  

He says the Joe Biden he was with three weeks ago wasn't the Biden of 2010.
