'It's called cover your ass': Trump allies reveal why everyone is secretly recording the president

From former aide Omarosa Manigault-Newman to , it seems that President Donald Trump has a real problem with people making secret recordings of their interactions with him.

In a new Vanity Fair article, sources tell reporter Emily Jane Fox that the reason so many people are recording the president is simple: Namely, he lies to them so much that they want to thoroughly document everything he says.

"It's called C.Y.A. -- cover your ass," former Trump aide Sam Nunberg explains to Fox. "That's why people are recording."

Another person whom Fox described as in Trump's "orbit" tells Fox that people who have taken Trump at his word have often found themselves getting burned after Trump denies telling them what he actually told them.

"It's because of his erratic behavior and his inability to tell the truth," the source said. "He changes his mind after the fact. He commits to doing something, only to have him question you after you do it."

In Cohen's case, it seems that the one-time "fixer" wanted proof that Trump had given him permission to pay hush money to a Playboy model because he feared that the president would then deny having ever given him permission as an excuse to avoid paying Cohen back.

"What ends up happening is you sit there, and you’re the one on the hook -- not him," one source explained to Fox. "That's why people tape him."
