The Department of Justice is withholding the audio from President Joe Biden‘s interview with former special counsel Robert Hur due to fears that it will be altered by artificial intelligence, according to a court filing.

CNN, the Heritage Foundation, and Judicial Watch, among others, have all been denied Freedom of Information Act requests for the audio and have subsequently filed suit against the Justice Department. In response, it issued a court filing Friday night to explain why it won’t release the audio from Hur’s interview with Biden.
