Omarosa Manigault-Newman recorded private discussions in the West Wing, one source reported to the Daily Beast the existence of the recordings, which appear to feature Trump's voice. While some of the conversations may contain mundane exchanges, the betrayal is sure to enrage Trump, who hates people taping him.
Omarosa's forthcoming book, UNHINGED, contains written excerpts of the tapes and it's possible she could release the audio at some point. The mere fact people have heard these tapes & confirm their existence should trouble Trump. Who else in the White House records Trump?
