Fox Corp boss Lachlan Murdoch is set to appear for a deposition hearing next week, as the defamation lawsuit against Fox News continues.
Dominion Voting Systems is suing Fox over false claims made in relation to voting machines, alleging they rigged the results of the 2020 election between Donald Trump and Joe Biden.
Dominion has argued the parent company played a role in Fox hosts in spreading misinformation about voter fraud, and is seeking $1.6 billion in damages.
Fox personalities including Tucker Carlson and Jeanine Pirro have already given evidence.
Requests to dismiss the case have been denied and neither side has shown signs of entering settlement talks.
