David Bookstaver, 58, was fired from his $166,000-a-year role in the Office of Court Administration after the New York Post reported that he revealed the information during an inadvertent butt dial.

New York State Chief Judge Janet DiFiore ordered an investigation “immediately following the revelation of David Bookstaver’s conduct.”

Bookstaver made the admission after the newspaper had asked him to address claims he showed up as little as two days a week at work.

In the voicemail he says: “I spoke to on the record for a while. I said, ‘I’m in a much less visible position; that doesn’t mean I’m not doing anything.’”

He added: “But, frankly, look, the bottom line: The story’s true. I’m not doing anything. I barely show up to work and I’ve been caught.”
