Trump — who continues to allege that the 2020 election was “rigged” against him, including recently in News Corps’ Wall Street Journal — should move on, billionaire Murdoch, 90, said during News Corp’s annual shareholder meeting on Wednesday.

“The current American political debate is profound, whether about education or welfare or economic opportunity,” said Murdoch, whose family controls Fox News’s parent company, Fox Corp. “It is crucial that conservatives play an active, forceful role in that debate, but that will not happen if President Trump stays focused on the past.”

“The past is the past, and the country is now in a contest to define the future,” Murdoch continued.

The two powerful men, who each command large audiences, have had a tumultuous professional relationship.
