The audio recordings of his conversations with the ghostwriter of his 2017 memoir were part of a special counsel probe into his alleged mishandling of classified documents.

Former President Joe Biden is trying to block the Department of Justice from releasing audio used in the special counsel probe that revealed his memory lapses.

In the lawsuit, Biden argued the recordings contain deeply personal discussions that should remain private.
