CNN boss Jeff Zucker may be ready for his close-up.

The boss of the left-leaning news network is said to be the “leading, if not only” internal candidate to become chief executive of WarnerMedia, the entertainment division of AT&T, according to a report.

Citing anonymous sources, NBC News said Tuesday that Zucker’s name is being shopped to head up the group, which includes Warner Bros., HBO and Turner Broadcasting.

Zucker would replace WarnerMedia boss John Stankey, who also holds the role of AT&T president and chief operating officer — a title he acquired earlier this month on top of his job as head of AT&T’s entertainment division.

Stankey denied NBC’s report, telling The Wall Street Journal on Tuesday: “I’m not looking to find my successor right at the moment.”

AT&T, which bought WarnerMedia, formerly known as Time Warner, in 2018, is trying to fend off Paul Singer’s activist hedge fund Elliott Management.

Elliott, which owns a $3.2 billion stake in AT&T, has questioned AT&T chief Randall Stephenson’s decision to tap Stankey as his heir apparent, saying the company failed to conduct a search for “the most qualified executives available” when naming Stankey president and COO “of the entire company.”

In an August report by The Post, employees blasted Stankey, who was then only head of WarnerMedia, for his lack of knowledge of Hollywood and his boorish, dismissive management style.

Even so, Zucker’s appointment could face headwinds due to his troubled relationship with President Trump.

Trump has called for the exec to be fired and repeatedly describes CNN as “fake news.” According to NBC, WarnerMedia insiders have wondered why AT&T would make itself a “bigger target for the administration” as it reportedly mulls selling businesses including DirecTV, which would require approval from US authorities.

WarnerMedia did not return calls seeking comment.
