Jessica Yellin has been promoted to chief White House correspondent at CNN, replacing Ed Henry, who jumped to Fox News on June 20 to take the same position. Yellin had been a national political correspondent at CNN. “Jessica’s assertiveness along with her clever insight made her one of the top reporters of the 2008 campaign and has already set her apart in her reporting on the 2012 campaign,” said CNN Washington bureau chief Sam Feist, who announced the move today. “We’re thrilled Jessica will now bring her outstanding political journalism to our White House coverage.” Before CNN, she had stints at ABC News and MSNBC.
