Michael Corn

Michael Corn, former senior executive producer of “Good Morning America” and a 19-year veteran of ABC News, has been tapped to run NewsNation, the Chicago-based cable news network, sources said Monday.

At a staff meeting Tuesday Corn is expected to be introduced as president of NewsNation by parent company Nexstar Media Group. He will report to Sean Compton, president of Nexstar Networks.

Jennifer Lyons

The top job at NewsNation has been vacant since March when Jennifer Lyons abruptly resigned as vice president of news.

Lyons's departure along with two other news managers was believed to be tied to conflicts between the network’s promise of impartiality and pressure to promote right-wing views. It followed the disclosure that Nexstar had retained Bill Shine, former Fox News senior executive and White House communications director for former President Donald Trump, as a consultant.

In hiring Corn, Nexstar landed a seasoned and respected network news veteran who oversaw the top-rated “GMA” for seven years and earlier served as executive producer of ABC’s top-rated “World News Tonight” with Diane Sawyer.

Capping nearly two decades at ABC News, Corn resigned last month — one day after he was passed over for promotion to president. That job went to Kim Godwin, a former senior executive at CBS News.

NewsNation previously disclosed plans to launch a five-hour morning show later this year.
