Trump also says in the 2021 clip that if we were still president he could declassify it. The clip contradicts Trump's claims that all the records he had were already declassified. In leaked audio from 2021, published Monday by CNN, former President Donald Trump is about as direct as he can be in acknowledging that he knows a document he has is "secret," that it has not been declassified, and that if he were still president he could declassify it.The audio appears to fly in the face of what has been Trump's defense since the FBI raided his Mar-a-Lago resort and residence last year: that he had declassified all the documents he had, even though there was no record of him having done so.The audio, obtained and published by CNN, was initially obtained by federal prosecutors investigating Trump's handling of classified documents.
