Former President Joe Biden's speech is marked with long pauses and a halting delivery in a recording of his interview about classified documents released Friday.

Newly released audio of a special counsel interviewing then-President Biden confirms memory lapses that White House officials denied at the time, including a president clearly struggling to remember the year his oldest son died.

Although a transcript of the interview had already been released, the recording is striking and fleshes out the picture of the high-stakes session.
