Frank Sesno, a former CNN Washington bureau chief, will rejoin the network with the title of "Special Correspondent."

"Frank has always stood for quality journalism," said Jon Klein, president of CNN's domestic network. "His walkabout in the real world has made him even more connected to the stories that affect viewers’ lives and more committed to the audience’s need for reliable, down-the-middle sources of information."

In addition to his role at CNN, Sesno will continue serving as a professor of public policy and communication at George Mason University.

"I want to connect the public to the people and issues that matter – that define us – through stories that have texture and impact," said Sesno. "Long-form television can capture the complexity and humanity of a story. It can cut through the noise and the clutter. It can tell a powerful story and make a difference."

Sesno had previously worked at CNN for 17 years, including seven as anchor of the network's flagship weekend programme Late Edition.
