Dominion Voting Systems is urging a Delaware judge to compel Fox execs Rupert Murdoch and Lachlan Murdoch to testify live in court.

Dominion Voting pointed to evidence that Fox News anchors expressed doubts in Donald Trump’s false claims of a rigged election in 2020.

Rupert Murdoch had been exploring a reunion of Fox and News Corp about 10 years after he split the companies.
