The attorney who moved to keep billionaire pedophile Jeffrey Epstein's sex abuse case secret from the public formerly represented Robert Mueller and ex-FBI Director James Comey.

Just before Epstein's case was set to be unsealed, former federal prosecutor Nick Lewin filed an amicus brief to the New York-based 2nd Circuit Court of Appeals objecting to the case's imminent unsealing.

He filed the complaint on behalf of "John Doe," claiming that unsealing the suit against Epstein could potentially name and therefore bring undo embarrassment to his client.

"Wholesale unsealing of the Summary Judgment Materials will almost certainly disclose unadjudicated allegations against third persons — allegations that may be the product of false statements or, perhaps, simply mistake, confusion, or failing memories of events alleged to have occurred over a decade and half ago," Lewin wrote in the brief filed Tuesday.
