Former Democratic US president Joe Biden is suing the Department of Justice, seeking to bar the release of audio recordings and transcripts of private conversations with his biographer.
The lawsuit, filed in federal court in Washington DC on Tuesday, comes ahead of the department's planned June 15 release of the materials to the US House Judiciary Committee and the conservative Heritage Foundation.
The foundation sought them after they were used as part of then-Special Counsel Robert Hur's 2023 investigation into Biden's handling of classified documents.
