Dominion claims Rupert Murdoch shared info about Biden ads with Trump's campaign in 2020.
"During Trump's campaign, Rupert provided Trump's son-in-law and senior advisor, Jared Kushner, with Fox confidential information about Biden's ads, along with debate strategy (providing Kushner a preview of Biden's ads before they were public)," Dominion's lawyers alleged in the filing.
"If the allegations are true, this is precisely what Murdoch provided to the Trump campaign," he said.
After Trump lost, Murdoch shifted attention to two runoff elections in Georgia for US Senate seats.
"My friend Jared Kushner called me saying, 'This is terrible,' Murdoch wrote.
