CBS News has hired a well-regarded TV veteran as its No. 2 executive — even as insiders speculate that the broadcast giant’s boss is on the way out. The Tiffany Network appointed former ABC News executive Tom Cibrowski to the role of president and executive editor of CBS News,

Tom Cibrowski, who oversaw ABC’s “Good Morning America” during one of its most successful eras, is joining CBS News as president and executive editor. The storied news division, which has been reeling over its legal battle involving President Trump, announced Thursday that Ciabrowski will oversee newsgathering and programming.

Wendy McMahon, president and CEO of CBS News and Television Stations and CBS Media Ventures, announced Cibrowski’s hiring Thursday morning. Cibrowski succeeds Adrienne Roark, the former CBS News president of newsgathering, who left for a job at Tegna earlier this month.

This marks a return to CBS News for Cibrowski, who earlier was a broadcast producer for CBS News' The Early Show.

Tom Cibrowski, who had top roles at ABC News, has been named president and executive editor of CBS News. Cibrowski’s appointment follows the exit of Adrienne Roark, who announced last week that she was going to Tegna for a senior role.
