Specifically, the subpoena from Smartmatic seeks by September 16 any communication Barr had with Fox News employees about the 2020 election, Trump campaign, or Smartmatic after January 1, 2020.
The subpoena also requires Barr to produce similar communication he may have had with Rupert and Lachlan Murdoch, who own the channel’s parent company, and Rudy Giuliani, who previously represented former President Donald Trump. Giuliani is a co-defendant in the same lawsuit.
And finally, the subpoena demands any documents or communication Barr provided to the House committee investigating the January 6 attack on the US Capitol.
Representatives for Smartmatic did not respond to requests for comment about the subpoena on Friday. Barr declined to comment to CNN.
A New York judge earlier this year rejected Fox News’ motion to dismiss Smartmatic’s defamation lawsuit, allowing the case to move forward to discovery.
The move to subpoena Barr comes just weeks after Dominion Voting Systems, another election technology company, subpoenaed him in its separate case against Fox News.
