Shari Redstone, the media mogul whose Paramount empire controls CBS News, criticized the network’s leadership on Wednesday for its decision to reprimand a star morning show anchor over his handling of an on-air interview with the writer Ta-Nehisi Coates.

“They made a mistake here,” Ms. Redstone said during an appearance in Midtown Manhattan, adding, “I think we all agree that this was not handled correctly.”

Her remarks have added to the turmoil that has swirled inside CBS News in recent days, especially after top executives rebuked the anchor, Tony Dokoupil, on a newsroom-wide call on Monday, saying his interview had fallen short of editorial standards.

Mr. Dokoupil had challenged Mr. Coates’s views about the Israeli-Palestinian conflict during a tense but civil appearance last week on “CBS Mornings,” at one point saying parts of Mr. Coates’s new book — which compares Israel’s treatment of Palestinians to Jim Crow laws — “would not be out of place in the backpack of an extremist.”

Asked directly on Wednesday if she believed Mr. Dokoupil’s line of questioning had violated CBS’s standards, Ms. Redstone replied, “No.”

“Tony did a great job with that interview,” she said at a panel at Advertising Week, a media industry conference. “I think he handled himself and showed the world a role model of what civil discourse is, that he showed that there was accountability, that there is a system of checks and balances, and frankly I was very proud of the work that he did.”
