Former Attorney General William Barr has been issued a subpoena in the defamation case between Dominion Voting Systems and Fox News.

The Hill reports:

A filing made in Delaware Superior Court and dated July 8 indicated Barr had been sent a subpoena as Dominion works to prove Fox knowingly aired false information about the company following the 2020 election.

Last March, Dominion filed a $1.6 billion lawsuit against Fox News, alleging the network intentionally aired defamatory claims against the voting company to spread claims that widespread voter fraud impacted the 2020 election.

Barr previously broke with Trump over his claims that voter fraud impacted the 2020 election, testifying that the Justice Department had not found evidence to corroborate Trump’s claims.

“My opinion then and my opinion now is that the election was not stolen by fraud,” Barr said during taped testimony played during a recent committee hearing, adding nothing he’d seen since then had changed his opinion.

In a recent filing, Dominion’s legal team argued Fox News owner Rupert Murdoch “decided to promote former President Trump’s narrative after Trump’s condemnation of Fox damaged its stock and viewership.”

Delaware Superior Court Judge Eric M. Davis last month denied a motion from Fox Corp. to dismiss the the suit, writing that the voting systems company “adequately states a claim for defamation per se against Fox Corporation based on its theory of direct liability.”

Fox has moved to dismiss the case on First Amendment grounds.
