WASHINGTON (AP) — Joe Biden sued the Justice Department on Tuesday in an effort to block the release of audio recordings and transcripts of the former president’s interview with a ghostwriter that were obtained by the special counsel who investigated his handling of classified documents.

Biden’s lawyers said in a lawsuit filed in Washington’s federal court that the Justice Department plans to release the files to Congress and a conservative group, the Heritage Foundation, after the department had previously argued that they were exempt from disclosure under the public records law.
