Ten days after the 2020 election, Fox News’ so-called Brain Room investigated conspiracy theories that Dominion Voting Systems had rigged the presidential election against Donald Trump.

The network’s fact-checking and research division came back with a clear decision: Those claims were false. But the misinformation went on the air anyway.

Details of the Brain Room fact check were revealed on Wednesday in newly released slides. from a Dominion filing, which the company showed at last week’s pretrial hearing in its $1.6 billion defamation lawsuit against Fox News and its parent company, Fox Corp. The slides cite internal communications and testimonials.

Fox News had redacted the «Brain Room» findings, but the judge on Tuesday ordered them made public.
