In the wake of the 9-11 terror attacks, King launched his daily editorial panel 'Funny Paperz' with the Santa Monica Daily Press in 2002. It ran in this paper for four years, until it was published throughout the US until 2006, and then again on a local basis until 2008. He was nominated for a Pulitzer in 2004 for his work covering the war in Iraq. As of 2009 he has returned to national news coverage online through the Association of American Editorial Cartoonists.
