Murdoch son is off board of News Corp.

James Murdoch resigned from News Corp.’s board of directors Friday, a dramatic sign that Rupert Murdoch’s youngest son is further defecting from his billionaire baron dad.

“My resignation is due to disagreements over certain editorial content published by the company’s news outlets and certain other strategic decisions,” James said in a letter filed with regulators.

James, 47, was CEO of the famed 21st Century Fox production studio from 2015 to 2019, until it was sold to the Walt Disney Company last year.

Since then, the remaining flagship Fox News

Channel has boisterously championed President Trump in the run-up to the November election. James, meanwhile, has showered his money on Democrats.

He and his wife Kathryn gave a combined $1.2 million to the Biden Victory Fund on June 30, money benefiting former Vice President Joe Biden’s White House run, according to the Federal Election Commission.

Rupert, 89, issued a short joint statement Friday with son Lachlan, the CEO of Fox Corporation, that wished James well.

“We’re grateful to James (below) for his many years of service to the company. We wish him the very best in his future endeavors,” they said.
