Audio of a 2021 meeting held at Trump's Bedminster golf club — in which he speaks of a classified document pertaining to a potential attack on Iran — is at the top of the pile of evidence in the ongoing investigation into his handling of sensitive materials post-presidency. Missing from that pile is the document itself, as his lawyers are unable to locate it.
In mid-March, a federal subpoena was issued asking for Trump's attorneys to hand over material related to the information discussed on the audio, but have yet to be able to produce the physical document that was referenced on it, which presents an even larger issue.
